INTRODUCTION (彳) TECHNICAL FIELD The present invention relates to semiconductor integrated circuit devices, and mainly relates to power supply control in Dynamic RAM (Random Access Memory). Effective technology. Background Art In order to increase the information retention time of a memory cell in a dynamic RAM, it is necessary to thin the impurity concentration of the substrate and reduce the address to select the electric field of the junction between the source and drain diffusion layers of the MO S F E T and the substrate. By reducing the impurity concentration of the substrate in this way, the critical threshold voltage of the above MO S F ET becomes lower, and the leakage current between the source and the drain when the gate voltage is set to a non-selected level such as the ground potential will increase. Therefore, it is suggested to set the non-selection level of the word line connected to the gate to a negative voltage. This negative voltage uses a charge pump circuit, and the oscillation circuit is intermittently operated by a level sensor in order to stabilize it. In this way, the non-selection level of the word line is set to a negative voltage to improve the information retention time. There are still dynamic RAMs such as Japanese Patent Application Laid-Open No. 2-5 2990, Japanese Patent Application Laid-Open No. 6-255566, Japanese Patent Application Laid-Open No. 7-5746 Bulletin No. 1 and Japanese Patent Application Laid-Open No. 7-30709. Due to the combination of the substrate voltage and the bit line or word line capacity, when the bit line or word line is changed between the selection level and the non-selection level, 10% to 30% will be generated. Large potential changes. Therefore, when the charge pump circuit uses the negative bias voltage supplied to the substrate voltage to use the non-selection level of the word line, by changing the capacity combination and the selection level of the word line to the current for the non-selection level, For the discharge, the non-selection level of the character line ^ paper size is applicable to China National Standard (CNS) A4 (210X297 mm)

The negative voltage V B B is set to be absolutely larger than the negative voltage V N N corresponding to a non-selection level such as the word line W 1. For example, as shown in the operation waveform diagram of FIG. 3, the non-selection voltage VNN of the word line is set to -0.75V, and the negative voltage VB B is set to 1.1V. A relatively large voltage in the negative direction is formed relative to the necessary voltage VNN, and the reference voltage generating circuit RG FN is operated according to the negative voltage VB B.

In this embodiment, the voltage VRN is set to a negative voltage of 10.75V. The fixed voltage generating circuit RGN is an N-channel type that is set as a variable resistance element between the negative voltage VB B and the internal negative voltage VNN. The MOSFET Q1 5 is composed of a differential amplifier circuit 9 that receives the reference voltage VRN and the internal negative voltage VNN. The output signal of the differential amplifier circuit 9 is supplied to the gate of the MOSFET Q15. It is controlled so that when the absolute value of the internal high voltage VNN is smaller than the reference voltage VRN, a signal that changes to a level is formed, and the resistance of the MOSFET Q1 5 is reduced to make the two coincide. Conversely, when the absolute value of the internal negative voltage VNN is greater than the reference voltage VRN, a signal that changes to the L level is formed, and the resistance of the MOSFET Q15 is increased to make the two coincide. The constant voltage generating circuit 5 receives the external voltage Vext from the external terminal, and generates the internal step-down voltage VDL by the same circuit as the above-mentioned constant voltage generating circuit RGP. The constant voltage generating circuit 5 is not necessarily required. The peripheral circuits such as the above-mentioned sense amplifier or address selection circuit may be operated by an external voltage V e X t supplied from an external terminal. In this case, as described above, the level of the internal high voltage V C Η is formed based on the external voltage V e X t as a reference. Even when the constant voltage generating circuit 5 is provided, the constant voltage VD L is used as the operating voltage of the sense amplifier, so that internal circuits such as an address buffer or an address decoder can operate according to the external voltage V e X t.

To estimate such voltage changes and set the selection level and non-selection level of the word line, it is necessary to select the gate insulating film of MO SFET at the address where the word line is connected, or drive the word line The voltage of the gate insulation film of the output MO SFET of the zigzag line driver is high-voltage resistant, corresponding to the voltage estimated to increase in the above-mentioned level variation.

In contrast, the invention in this case is designed to select the word line through the constant voltage circuit RG P or RGN Level, non-selection level, as described above, when the character line is cut from the non-selection level to the selection level, or vice versa, the selection level is cut to the non-selection level. The charge or discharge current of the word line of parasitic capacity causes changes in VPP and VBB. However, since the resistances Q of the variable resistors MOSFETs Q12 and Q15 of the constant-voltage circuit RGP or RGN also change to absorb the voltage variation, approximately constant voltages V C Η and VNN can be ensured.

FIG. 3 is a waveform of a description of a rough operation of the dynamic Ram according to the present invention. The diagram mainly illustrates a selection operation of a memory cell. The equalization signal E Q is set to the level of the above-mentioned internal high voltage VCH when the memory cell is in the information holding state. In this way, the MOSFETs Q1 to Q3 are turned on, the complementary bit lines b i t and / b i t are short-circuited, and the above-mentioned half precharge voltage VDL / 2 is supplied. Since the complementary bit lines b i t and / b i t are set to a half pre-electric voltage VDL / 2, the level of the equalization signal EQ will operate even at a low potential of V D L. However, as in this embodiment, by using the internal high voltage VCH ', the ON resistance of the MOSFET Q1 can be reduced, and in a short time, the bit level of the complementary bit line bit and / bit can be short-circuited to the L level to set the intermediate potential. VDL / 2. When the memory is accessed, the equalization signal E Q changes from the Η level to the L level. At this time, the L level of the equalization signal E Q is not the ground potential of the circuit, but a negative voltage VNN. The reason is that the threshold value 较小 is set to be small in order to increase the equalization speed, and a negative voltage V N N is supplied to the gates of the MOSFETs Q1 to Q3 to prevent leakage current flowing between the drain and source. As described above, the active signal SAN of the sense amplifier is set to a negative voltage V N N when the sense amplifier is in an inactive state to prevent leakage current flowing through the power switch MOSFET Q8. That is, in order to increase the speed of the sense amplifier, the MOSFET Q8 has a thin gate insulating film and is set to a low threshold voltage.

Description of the invention (u) The threshold voltage M 0 SFET can flow a larger current during operation. The amplifier's amplification action is high speed. In this case, the same is true for the P-channel MOSFET Q9. When the sense amplifier is in the inactive state, it is set to the internal high voltage VCH to prevent the leakage current flowing through the power switch MOSFET Q9. When the equalization signal E Q is set to the non-selection level of the negative voltage V Ν Ν, the word line Wi becomes the selected state of the Η level of the internal high voltage ν C Η. In this way, the address selection of the memory cell M 0 SFETQ m becomes 0 Ν state. The charge dispersion is performed between the parasitic capacity of the information memory capacitor Cs and the bit line bit or / bit set to the above-mentioned semi-precharge potential VD L / 2 . For example, when there is no charge state in the capacitor C s recorded in the information, the potential of the bit line connected to the memory cell decreases as shown in the figure. The sense amplifier can actuate the signal S A N, which rises from the negative voltage VNN to the internal step-down voltage VDL as described above, so that the N-channel MOSFET Q8 is turned on and supplies the operating voltage of the L level of the ground potential of the circuit. The activation signal SAP of the sense amplifier drops from the internal high voltage VC to the L level of the circuit ground potential VSS, sets the P-channel MOSFET Q9 to the ON state, and supplies the operating voltage of the internal step-down voltage VD L to a high level. . As mentioned above, the MOSFET Q8 and Q9 have thin gate insulation films and are set to a lower threshold voltage. Therefore, when set to the ON state, a larger current flows to make the amplification of the sense amplifier at high speed.

Description of the invention (12) The read potential difference in the above-mentioned billion grids is enlarged, and enlarged to the internal level of the step-down voltage VD L and the L level of the potential ground potential. Due to the amplification action of the above-mentioned sense amplifier, corresponding to the bit level and L level of the complementary bit line bit and / bit, the memory cell connected to the bit line bit and / bit is selected by the selection action of the word line Wi. One hundred million capacitors Cs are written into the L level corresponding to the state of the stored charge again. After the memory access is completed, the word line Wi drops from the internal high voltage VCH to the negative voltage VNN. After that, the equalization signal EQ rises from the negative voltage VNN to the internal high voltage VCH, making the complementary bit lines bit and / bit The level / L level is short-circuited to set the half precharge voltage VDL / 2. In order to prevent the half-precharge voltage VDL / 2 thus formed from changing due to leakage current, MOSFETs Q2 and Q3 are provided, and the half-precharge voltage VD L / 2 is transmitted to the complementary bit line bit and / by its ON state. bit.

The peripheral circuits such as the X decoder are PWE L L formed in the P-well area on the P-substrate. According to this structure, including the PWE LL of the N-channel type M0 s FET with a memory cell or a sense amplifier, the sense amplifier, the memory cell, and the megacell can be recorded without setting separate component separation areas. The character driver is formed in the DWE LL at the same time, so as to achieve high integration. In this embodiment, the MOSFET has two types of gate insulating film 'MO SFET of memory cell address selection' and a character driven output MO SFET. The gate insulating film is formed as the thicker film thickness t ο X 2 . The sense amplifier or the MO S F E T ′ constituting the peripheral circuit is formed as a gate insulating film having a thinner film thickness t oxl. The advantage of using two kinds of gate insulation film thickness is that it can achieve both the reliability of the device and the high-speed operation. In other words, when there is one type of gate insulating film, in order to ensure the reliability of the device (guaranteed the withstand voltage of the gate insulating film) under the maximum applied voltage condition, the film thickness of the gate insulating film is limited. In the above-mentioned high-voltage circuit, the critical threshold voltage becomes higher, the current driving capability is lowered, and the operation speed becomes slower. In particular, peripheral circuits and sense amplifiers are greatly affected by the driving ability of M 0 S F E T.

The inverter circuit I V 1 is shown as a part of the level conversion circuit L S P, but it is actually only used as an inverted signal forming the output signal of the X decoder D EC. Therefore, the level conversion circuit LSP operates on the high-voltage VCH and the ground circuit of the circuit as described above, but the converter circuit IV 1 also operates on the internal step-down voltage VD L and the ground potential VSS like the X decoder XD EC. . Printed by the Consumer Standards Cooperative Bureau of the Ministry of Economic Affairs (Please read the precautions on the back before filling out this page) The level conversion circuit L S N has the same circuit configuration as the level conversion circuit LSP. Therefore, the difference is that the P-channel MOSFET is the opposite of the N-channel MOSFET. The N-channel MOSFET is provided with a latching M 0 SFET. At the same time, the operating voltage on the level side is replaced by the internal step-down voltage VDL. The voltage VCH, the operating voltage on the L level side replaces the ground circuit VSS of the circuit with the internal negative voltage VNN. That is, the level conversion circuit LSN is set to operate with the internal step-down voltage VD L and the internal negative voltage VNN, and is provided with a pair of P-channel type MO SF ET and N-channel type MO SFE Τ which is the same as the above. The CMO S converter circuit and the P-channel type MO SF Ε Τ are connected in series, and the gates supply the output signals of another CMO S converter circuit to each other, and the N-channel type MOSFET set to the latching mode is supplied. There is an internal negative voltage V N N. The output signal N1 of the X decoder XDEC is supplied to the gate of MO SF Ε T which constitutes one CMO S converter circuit.

Description of the invention (18) The circuit is reversed and supplied to the gate of the MOSFET of the other party ’s CMO S converter circuit. The output signal N 2 of one inverter circuit is supplied to the input of the CMO S inverter circuit acting as a driver. The output signal N 3 of the inverter circuit is to the gate of the N-channel output MOSFET MN1. To drive the output MOSFET MN 1. In this embodiment, in order to reduce the voltage applied between the gates and the drains of the outputs MO SF Ε Τ MP1 and MN1, in other words, to alleviate the stress applied to the gate insulating films of the MOSFETs MP1 and MN1, P-channel MOSFET MP2 and N-channel MOSFET MN2 are connected in series between the output terminals connected to the element line Wi. A ground potential VSS is applied to the gate of the P-channel MOSFET MP2 to always be turned on, and the N-channel MOSFET MN2 An internal step-down voltage VD L is applied to the gate to be always ON. The level conversion circuit LSP is used to form the driving signal N5 of the signal amplitude of VCH and VSS to control the ON / OFF state of the output MOSFET MP1. The P-channel MOSFET MP2 can keep the drain voltage of the output MOSFET MP1 at the ground potential VSS + VT (where VT is the critical threshold voltage of the MOSFET MP2) even when the word line Wi is a negative voltage VNN. 0 Result As shown in the operation waveform of Fig. 7, even if the output terminal is a character line Wi due to the ON state of the N-channel output MOSFET MN1, the paper bearing standard is applicable to China National Standard (CNS) A4 specification (210X297 mm) -21- (Please read the precautions on the back before filling out this page)..,-'° A7 ____ B7 V. Description of the invention (19) When the negative voltage VNN corresponding to the non-selection level, the P channel output at 0FF state Only the voltage of VCH- (VSS + VT) is applied between the gate and the drain of the MOS FET MP 1. The level conversion circuit L S N is used to form the driving signal N 3 of the amplitude of the signals of VD L and VNN to control the ON / OFF state of the output MO S F E T MN1. Therefore, even when the word line Wi is a high voltage VCH, the N-channel MOSFET MN1 can keep the drain voltage of the output MOSFET MN1 at the internal step-down voltage VDL — VT (VT is the threshold voltage of the MOSFET MN2). As a result, as shown in the operation waveform diagram of FIG. 7, when the output terminal is the internal high voltage V c 对应 corresponding to the selection level of the word line Wi due to the ON state of the P-channel MOSFET MP1, the N channel is in the OFF state. Only the voltage (VDL-VT)-VNN is applied between the gate and the drain of the output MOSFET MN1. Dumpling Packing for Shellfisher Consumer Co-operation, Central Bureau of Standards, Ministry of Economy The limiting effect of the signal amplitudes of the driving voltages N 5 and N 3 is multiplied by the applied voltage division effect of the MOSFETs MP2 and MN 2 arranged in series, so despite the selection level / non-selection of the word line Wi The level is a relatively large voltage corresponding to the internal high voltage VC Η and the internal negative voltage VNN, but the voltages applied to the output MOSFETs MP1 and MN1 can be suppressed to be small. Therefore, as far as the memory cell is concerned, the internal step-down voltage VD L is kept at the storage capacitor Cs. Therefore, when the character line Wi is set to a non-selected negative voltage VNN, the paper size is based on Chinese standards (CNS} A4).

Description of the invention (20) The maximum voltage of VNN — VD L is applied, and when the character line wi is set to the selection voltage V After CH, the maximum voltage of VSS _V CH is applied to the level conversion operation of the level switching circuit LSP. The following is a summary. When the output signal N 1 of the gate circuit G 1 forming the X decoder XD EC corresponds to the ground potential VSS When the L level is on, the P channel MOSFET Q 1 9 of one CMO S converter circuit (Q1 7 and Q1 9) is ON. The 信号 level of the output signal of the inverter circuit IV 1 makes the N channel type The MOSFET Q16 is in the ON state, so the output signal of the other CMOS inverter circuits (Q 1 6 and Q 1 8) is at the L level. Accordingly, the p-channel MOSFET Q2 1 is set to the ON state, The MOSFET Q19 in the ON state sets the output signal N 4 to the high level of the high voltage VCH. As a result, the The high voltage V CH corresponds to the high level, and the P-channel type MO SF ET Q20 is set to the OFF state, so that the DC current does not flow through the other C Μ 0 S converter. When the X decoder C gate is formed When the output signal N 1 of the pole circuit G 1 is at the level of the internal step-down voltage VDL, the N-channel MOS FET Q 1 7 of one of the CMOS converter circuits (Q 1 7 and Q 1 9) becomes ON. On the other side of the CMO S inverter circuit (Q16 and Q18), the output signal of the inverter circuit IV1 becomes the L level, and the P-channel MOSFET Q18 is turned on. The output signal N4 is set to L because the MOSFET Q17 is turned on. Level.

Description of Invention (21) Therefore, the output signal of the CMO S converter circuit of the other party is set to the high level corresponding to the high voltage VCH. As a result, the P-channel MOSFET Q 2 1 is in the 0 F F state, so that a direct current does not flow through the CMO S converter circuit forming one of the L-level output signals N 4. The level conversion operation of the level conversion circuit LS Ν is almost the same as the above, so only the output signal N 1 of the gate circuit G 1 constituting the X decoder XD EC will be described below as the L level timing corresponding to the ground potential VS S Action. The P-channel type MO S F E T of the CMO S converter circuit supplied with one of the output signals N 1 is set to the 0 N state. The CMOS converter circuit of the other party is supplied with the inverted level signal, so the N-channel MOS F ET becomes ON. Due to the ON state of the P-channel type MO SF Ε T of the CMOS converter circuit of one side, the output signal N 2 becomes the level of the internal step-down voltage VD L, which makes the N-channel type of the CMO S converter circuit of the other side MO SF Ε Τ becomes ON. As a result, the output signal of the CMO S converter circuit of the other side is turned on because two N-channel type MO S F E T are turned on, and a negative voltage VNN is output. As a result, an output signal N 2 corresponding to the internal step-down voltage VD L can be formed, so that the N-channel type M 0 SF Ε Τ corresponding to the negative voltage VNN side becomes 0 FF state, so that the direct current does not flow through CMO S converter circuit on one side. FIG. 8 is a circuit diagram of another embodiment of the word line driver WD. In this embodiment, the X decoder is divided into two circuits. A four-word selection signal N1 is formed at the first decoder XDEC. The selection signal is a selection signal X 〇 formed by a second decoder (not shown).

Invention Description (22) X01, X10 and XII are used to control the switching MOSFETs Ml 0 ~ Ml 3 for the corresponding ones Character drive WD i. The word driver WD i 'is represented by a circuit, and has both the level conversion function and the character driving function. "-P-channel output MOSFETs M3 and M4, N-channel MOSFETs M6 and M5. Drivers. The N-channel type output MOSFET M6. Is latched with the N-channel type MOSFET M 7 and has a level switching function. The MOSFET M7 is connected in series with an N-channel MOSFET M8 for withstand voltage relaxation, and the MOSFET M5 is provided with an internal step-down voltage V D L at the gate. The P-channel output MOSFET M3 is a level-switched P-channel MOSFET M2 with a latching configuration. The gate of the output MOSFET M3 is pre-charged at a high voltage by the P-channel MOSFET M1 controlled by the precharge signal WPH. VCH. At its input point, a selection signal N 5 is supplied through a switching MOSFET M10. FIG. 9 is a timing chart illustrating the operation of the character driver. When the precharge signal WPH is at the L level of the circuit ground potential GND, the P-channel MOSFET M1 is turned on, and the input terminal is precharged to a high voltage VCH. The MOSFET M3 is turned off due to the precharge operation, and at the same time, the gate potential N 3 of the N-channel output MOSFET M 6 is set to the level of VD L-VT through the MOSFET M 9 ′ MOSFET M8 in the ON state.

Description of the invention (23) M 0 SFET M6 becomes ON state, making the word line Wi become the non-selection level of negative voltage VNN. Because of the ON state of MOSFET M6, The gate of the MO SFET M7 that is set to the latched state is supplied with a negative voltage VNN and becomes an FF state. Therefore, the through current can be prevented from flowing through the precharged MOSFET M1 that becomes the 0 N state, and the ON state is always used for voltage relaxation. The MOSFETs M9 and M8 and MOSFET M7 are connected in series. In the Ministry of Economic Affairs, the quasi bureau, the shellfisher, consumer cooperation, Du printed, because the X decoder operation, the first decoder XD EC 1 output signal N 1 becomes L level. After that, the MOSFET M10 is turned on because the selection signal X00 is at the Η level among the 4 word lines. Therefore, the selection signal N 5 at the input terminal may be at the L level. As a result, the output MOSFET M3 is turned off. The state is changed to the ON state, so that the word line Wi rises from a negative voltage VNN to a high voltage V CH Because of this voltage rise, MOSFET M7 becomes ON state, and the gate voltage N3 of MOSFET M6 decreases from VDL-VT to negative voltage VNN. Therefore, MOSFET M6 is set to OFF state, and the potential of word line Wi is fast. Rise to high voltage v C Η. For other non-selected word lines, the precharge voltage is maintained in the corresponding word driver. Therefore, the P-channel output MOSFET is turned OFF and the N-channel output MO SF Ε Τ is turned ON. The non-selection level of the negative voltage VNN is maintained. At the end of the selection operation of the word line Wi, the decoder signal χ〇〇 is set to the L level, and the MOSFET M10 is set to the OFF state. -26- (Please listen first (Please read the notes on the back and fill in this page again) This paper size is applicable to China Standard S (CNS) A4 (210X297 mm) Printed by A7 B7, Shellfish Consumer Cooperative, Central Samples Bureau, Ministry of Economic Affairs In addition, the output signal N 1 of the first decoder XDE C 1 is restored to the 之后 level. After that, the precharge signal WP Η becomes the L level, so that MO SF Ε Τ Μ 1 is turned ON. Therefore, the input terminal The voltage N 5 is precharged to a high voltage VCH. Because of this precharge action, P Channel type output MOSFET M3 OFF state, while the gate voltage of the N-channel MOSFET M6 \ 3 by MOSFET M8 set to VDL - Η limited level of VT. Due to the ON state of the MOSFET M6, the selection level (VCH) of the word line Wi rises to the negative voltage VNN corresponding to the non-selection level. In this configuration, the voltage applied to the output MOSFET M3 or M6 is limited as described above, so that high reliability of the device can be ensured. In this embodiment, for the first X decoder circuit XDE C, the word driver corresponding to the four word lines is shared. In this way, the number of MO S F E T necessary for one line can be reduced. In other words, the pitches of the word lines arranged at high density and the pitches of the X decoders forming the selection signal can be made consistent ', making high integration possible. Fig. 10 is a structural diagram of an embodiment when the present invention is applied to a hierarchical (divided character line) character driver. Hierarchical character lines refer to those that divide character lines into main character lines and sub-character lines, and connect the sub-character lines to the billion-character grid. In such a hierarchical character method, a high-resistance character line is made of a low-resistance metal wiring layer as a bottom layer to alleviate the wiring restriction of the metal wiring layer in the so-called character shunt method. With this type of segmented character line, a large memory capacity and a high accumulation can be achieved. The figure shows the relationship between the main character line and the auxiliary character line of the memory block. = ^^ 1 111.

In this embodiment, similarly, the differential amplifier circuit is composed of two circuits. A circuit composed of differential MOSFETs Q50 and Q51 and a MOSFET Q52 as a variable resistance element is a circuit in which the gate of the MOSFET Q43 that forms an operating current is always applied with the ground potential of VSS to operate normally. That is, in order to reduce the current consumption of the constant voltage generating circuit itself when the memory circuit is in the standby state, the paper size of the MO SFET is applied to the Chinese National Standard (CNS) A4 specification (210X297). Cooperative printed A7 B7 V. Description of the invention (36) Q 5 3 Only small current flows "is the switching of the selection / non-selection action corresponding to the character line accessed by the memory +, so that it has a larger current supply capacity. The P level MOSFET Q58 is set to ON state by the L level of the control signal AC TN. When the memory is accessed, the differential MOSFETs Q54 and Q4 are used, and the MOS F ET Q 5 is used as a variable resistance element. 6 The constant voltage circuit constituted operates. In this circuit, when the signal A C TN is in a non-operation state of Η level, the N channel type M 0 S F E T Q 5 7 is turned on, and the MOSFET Q56 used as a variable resistance element is turned off. Fig. 20 is a circuit diagram of an embodiment of the charge pump circuit 7 for VB B. In this embodiment, although not particularly limited, it may be constituted by P-channel MOSFETs Q59 to Q66. The P-channel type MO S F ET system is formed in the field of N-type wells. Therefore, it can be electrically separated from the P-well area where the memory grid is formed. In the operation of the charge pump, a few carriers will be generated in the N-well area, so it will not have any impact on the memory cells formed in the P-well area. A basic circuit of a capacitor C13 formed by using a MOS capacity and a pumping circuit that generates a negative voltage VBB by using MOSFE T Q6 1 and 63 is formed. Capacitor C14 and MOSFET Q62 and Q 6 4 are the same basic circuit. The input pulses 0 SC and 0 SCB have an inverse relationship between the active levels and do not coincide with each other. They correspond to the input pulse interaction to perform a highly efficient charge pump operation. . MOSFETs Q6 1 and Q6 3 are basically in the form of diodes m 'n ^ ii I 11 n ^ ik — ^ n In ml one eJ (read the precautions on the back before filling this page) This paper size applies to Chinese national standards (CNS) A4 specification (210X297 mm) -39- Duty printing of A7 B7 by the Central Bureau of Standards, Ministry of Economic Affairs, A7 B7 __— 15. Description of the invention (37), so only the level loss of the critical voltage is generated. When the high level of the pulse signal OSC is a low voltage of 3.3V, it does not substantially operate. Therefore, focusing on the case where the input pulse OSC is at the L level, the MOSFET Q61 can be set to the ON state, and the inverter circuit N10, the capacitor C 1 1 and the switching MOSFET Q59, which can form the same pulse as the input pulse, are set. To form a negative control voltage. In this way, in the state of no level loss, the negative potential of the capacitor C 1 3 can be transmitted to the substrate voltage VB B side. When a negative voltage is formed by the input pulse OSCB of the other party, the MOSFET Q59 is turned on to charge the capacitor Cl1. The capacitor Cl 1 is a capacitor of a small enough size to form the control voltage of the MOSFET Q61. MOSFET Q63 is set to 0 FF state at an earlier timing because it accepts the input signal from the other side at the deep gate (channel part). SCB's drive inverter circuit N 1 3 So that the discharge efficiency of the substrate potential is better. Similarly, the deep gate of MOSFET Q6 1 is supplied with the output signal of the drive converter circuit N 1 2. When the capacitor C 1 3 is charged, the MOSFET Q61 is turned off at an earlier timing and the substrate potential is The leakage current of VBB is the smallest, and it is supplied to the other side. The control voltage of the gate of MOSFET Q6 2 corresponding to the input pulse 0 SCB, and the deep gate voltage of MOSFET Q6 4 and Q6 2 are also used. According to the inverter circuit N 1 that performs the same operation 3 and the capacitor C 1 4 and the pulse signal formed by the input pulse 0 SC. Packing ------ order (please read the notes on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 specification (210X 297 mm) Cooperative printed B7____V. Description of the invention (38) MOSFET Q65 (Q66) is provided to discharge the alarm voltage of MOSFETs Q59 and Q63 (Q60 and Q64) at an earlier timing. The MOSFET Q 6 5 (Q 6 6 ), The gate and the drain are connected together to form a diode, and at the same time, the deep gate is supplied with the output signal of the drive inverter device N12 (N13) for receiving its own input pulse 0 sc (OSCB), For example, the MOSFET Q63 (Q64) is used for complementary switching control. In this way, when the output signal of the drive inverter circuit N1 2 (N1 3) changes to the L level in response to the input pulse 0 sc (OSCB), the MOSFET Q 6 3 (Q 6 4) can be turned ON earlier. By switching to the OF F state, the substrate potential can be effectively discharged to a negative voltage. Fig. 21 is a circuit diagram of an embodiment of an oscillating circuit 6 forming an oscillating pulse of a charge pump circuit 7 for VBB. In this embodiment, the P-channel MOS FET Q6 3 and the N-channel MO S FET Q70 constituting the CMOS inverter circuit are connected in series with a P-channel MOSFET Q68 and an N-channel MOSFET Q69 as resistive elements, respectively, to form a secondary circuit. The input capacity and time constant circuit of the CMOS inverter circuit of the segment perform signal delay. An odd number (5 in the figure) of the CMOS inverter circuit is connected vertically to form a ring oscillator. In order to make the ring oscillator operate intermittently, in other words, when the substrate voltage VBB reaches the required negative voltage (about 1.0V), the operation of the oscillation circuit is stopped to stabilize the substrate voltage VBB and low power consumption (please listen first Read the notes on the back and fill in this page again.)

The signal D E TA is a signal formed by the level sensing 1 1 I device described later. When it is judged that the substrate voltage VB B reaches the desired level, the 1 1 I is set to the L level. Due to the L level of the signal DE TA, the output signals passing through the inverter y-s. Please make the 1 1 N 1 5 and N 1 6 output signals to the L level. The back side of the CMO S inverter circuit as a resistance element I 1 N channel type M 0 S FET is set to OFF state, and at the same time, the P channel type MOS FE set at the output end of -dr 1 I is set to ON. State, forcing the most ψ term to 1 1 and the final stage output to be fixed at the Η level. That is, make the output of the gate circuits G 1 and G2 fill in the Η level, make the output signal of the gate circuit G 3 be the L level, make the oscillation pulse page 1 1 punch 0 SC, and make the oscillation pulse 0. SC Β is fixed at the Η level. 〇1 signal V Β 0 SC SW, when the memory is in the standby state, it is a 1 I Η level signal. Because of the high level of the signal VBOS C SW, the gate circuit 1 is ordered | G 1 turns off the sense electrode, and the gate circuit G 2 turns on, instead of the ring oscillator 1 1 forming a higher frequency y and using the built-in self-excited regeneration timer oscillation pulse 1 1 SL 0 SC as the oscillation pulse for the charge pump circuit 0 SC, 1 1 〇 SCB is used. Even in such a low-frequency charge pump circuit operation, due to the L level of the I signal DE T Α, the gate of the gate circuit G 2 switches the oscillation pulse 1 1 0 SC to the L level, and the oscillation pulse 0 SC Β is fixed at the Η position. quasi. 1 Figure 2 2 is a circuit of an embodiment of the level sensor 8 for V Β Β 1 1 Figure 0 N-channel type 1 | 〇 SFETQ 7 2 formed by applying a constant voltage VRE F 0 between the gate and the source Constant current, and based on the current mirror circuit 1 I to form a reference. Current i 1. A plurality of N-channel type 1 I M 0 S F E T are connected in series to the current path to supply the substrate voltage VB Β. Most of the 1 M 0 SFETs connected in series are provided with adjustment terminals, which are used to change the process of the components. 1 1 1 The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -42- Central standard of the Ministry of Economic Affairs Printed A7 B7 of Beihai Shellfish Consumer Cooperatives 5. Description of invention (40) Adjustment. That is, when the substrate voltage VBB is -1.0, the current i 2 and the current i 1 flowing through the series MOSFET are balanced. That is, the source potential of the MOSFET Q76 is made to be the same as the ground potential, so that the current i 2 and the current i 1 flowing through the MOSFET Q76 are adjusted in balance. In order to make the adjustment of the reference current i 1 possible, two MOSFETs Q73 and Q74 are connected in series to the N-channel current mirror circuit, and the current ratio of the current mirror is adjusted by selectively shorting the source and the drain. When the absolute voltage of the substrate voltage V B B is smaller than the set voltage, the source potential of the MOSFET Q 7 6 becomes higher than the ground potential, and has a relationship of i 2 > 1 1. In this way, the P-channel MOSFET Q76 connected in parallel with the P-channel MOSFET Q76 flowing the reference current i 1 has no current flowing, and corresponds to the current difference between the N-channel MOSFET Q78 flowing the current corresponding to the current i 1. The voltage vs is set to the L level. The signal V of the L level is amplified by a CMOS inverter circuit composed of MOSFETs Q68 to Q71, and then passed through the inverter circuit and the gate circuit G 4 as a sensing output DETA. Due to the high level of the sensing output D E TA, a current path is formed in parallel with MO S F E T Q 7 8, and the signal ν s is further decreased toward the L level side. When the absolute potential of the substrate potential V Β Β is greater than the voltage to be used, the current i 2 > i 1, the current differentially flows through the P-channel MOSFET Q77, so that the voltage vs rises to the Η level side. When the potential ν s is greater than the logic threshold C of the CMO S converter circuit, the sensing output D Ε ΤΑ becomes the L level and returns to the voltage ν s toward the L level side ^ 1 'n —I- · 1 ^ — ^ 1 »»--In 1-:--τ »-'s (Please read the precautions on the back before filling out this page) This paper size is applicable to China's Standards (CNS) A4 (210X297 mm) -43- The Central Bureau of Standards, Ministry of Economic Affairs, Shellfish Consumer Cooperation, Du printed equipment A7 B7__ V. Description of the invention (41) The N-channel MOSFET is turned off, causing the voltage vs. the voltage to rise rapidly to the high level. By using this feedback circuit, the level judgment of the CMO S inverter circuit has hysteresis characteristics. Therefore, the hysteresis characteristic can be controlled to stabilize the intermittent operation of the oscillating circuit and stabilize the substrate voltage VB Β within a range of 10% of the set value. The signal S ETB is a signal that is temporarily at a high level after the power is turned on. Because the level of the signal S Ε Τ Β forces the detection to detect that D Ε Α is at a high level to start the oscillation circuit. The voltage V S S or V S P is used as a bias voltage when a low-current consumption CMOS inverter circuit is used to determine the level of the voltage ν s / L level. Fig. 23 is a circuit diagram of an embodiment of the charge pump circuit 2 for VPP. In this embodiment, in order not to be affected by the fluctuation of the power supply voltage supplied from the external terminals, a stable high voltage VP P is generated, and the internal step-down voltage VD L is used as the operating voltage. When the oscillation pulse 0 S CH is at the high level, the capacitors C8, C9, and C10 are charged until the internal step-down voltage VD L is reached. During charging, the voltage MOS F E T for charging the boosted voltage formed by the capacitor C 7 is set to the ON state, so the VD L charging voltage can be performed in a state where there is no critical voltage drop. When the oscillating pulse 0 S CH becomes the L level, the capacitor C 7 generates a boosted voltage of 2 VDL while charging the capacitor C 7. Because the operating voltage of the CMOS inverter circuit composed of MOSFET Q71 and Q72 is set to the boost voltage of 2 VD L formed by capacitor C 9, the voltage of 2 VD L is supplied to capacitor C 8, so the boost of 2 VDL The voltage is 3VDL boost voltage VPP / make 1 ^ 1- n 1 ^ 1 In HI an-HI n I an (Please read the precautions on the back before filling this page) This paper size applies to China National Standards (CNS) A4 specifications (210X297 mm) -44- Printed by the Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, printed A7 B7 V. Description of the invention (42) The MO SFET for output becomes ON state. In this way, the boosted voltage of 2 VD L formed by the capacitor C 10 is output as the boosted voltage V P P without a level loss. Because the internal step-down voltage VDL is about 1.5 V, in the above embodiment, the charge pump circuit can form a boost voltage V P P of up to about 3 V. In this embodiment, the step-up voltage VPP may be 2.6V, so the step-up voltage of the oscillating circuit described later is used to generate a step-up voltage VPP of 2.6V. FIG. 24 is a circuit diagram of an embodiment of the oscillating circuit 1 for VPP.

A MOSFET Q73 is provided at the M 0 S F E T Q7 2 to supply a start signal NSENB temporarily set to the L level when the power is turned on. In the normal state, the MOSFET Q73 is ON, and the boost voltage VPP is divided by the resistance ratio with the N-channel MOSFET Q74. The logic threshold of the inverter circuit composed of N-channel MOSFET Q76, Q77 and N-channel MOSFET Q78 is used to determine the divided voltage. That is, when the boosted voltage VP P is greater than the set voltage, the divided voltage becomes greater than the logic critical voltage, forming an L-level output signal, which is amplified by the 2-stage CMO S converter circuit to increase the sensed output DE.

When the boost voltage VPP is less than the set voltage, the divided voltage becomes less than the logic threshold voltage, forming a high-level output signal, and amplifying it through the CMO S converter circuit of the two stages to make the output D Ε ΤΗ become Η Level. Accordingly, the operation of the oscillation circuit is restarted.

On the other hand, the decoder signal X i can also be expanded from 4 types to 8 types, and a character driver of 8 divided word lines can be used. In this case, the wiring pitch of the X decoder can be relaxed. Therefore, by expanding the level conversion circuits L S P and L S N in the horizontal direction, the vertical size of the wiring pattern (the extending direction of the character lines) can be reduced. Fig. 28 is a voltage characteristic diagram of an embodiment illustrating the relationship between the external calendar and the internal voltages VCH, VNN, and VDL in the dynamic RAM of the present invention. Generally, in the semiconductor memory, in order to screen out the initial defective products before shipment, a higher voltage than the normal use voltage must be applied to remove the defective components, which is the so-called aging test or pre-type test. In this embodiment, in order to make the test easy and improve the yield of the test, the gate insulation film is set to two types as described above, so that V CH and VD L are at a certain level with the external power supply voltage. Rise proportionally, switch the level difference between the standard action field and the warm-up test. On the other hand, the negative voltage VNN ′ is independent of the external voltage and remains at a certain level. Therefore, it can be set to a large value during preheating. The difference between V CH and V D L can be increased by increasing the slope of the voltage change. However, when the above method is adopted, VCH can be easily realized only by switching the resistance 値 of the resistance RL 2 in FIG. 17 to two stages, which is an advantage. With this kind of voltage switching, the voltage can be set accurately in both the standard operation field and the preheating field, which can prevent the damage of the component caused by excessive stress, and as a result, the yield can be improved. The above VDL is equal to the external voltage V e X t. -------- I— (Please read the notes on the back before filling in this paper.

Description of the invention (47) Figure 2 9 is a voltage characteristic diagram of another embodiment of the relationship between the external voltage and the internal voltage VCH, VNN, VDL in the dynamic RAM of the present invention. This embodiment When the external power supply voltage is set to 2.5 V, the voltage limiter is used to reduce the voltage, and the internal voltage in the standard operating field 乂 01 ^ is set to 1.5 乂. The same type and the same thickness as in the embodiment of FIG. 2 8 can be used. Gate insulation film. Among the above two types of MOSFETs, MO SFETs with thicker gate insulation films can be used as input buffers or output buffers in addition to character drivers or memory cells. Thinner gate insulation films The MO SFET is used as a peripheral circuit or a sense amplifier. The above-mentioned V CH and VD L are maintained near a standard operation area regardless of the external power supply voltage and remain in a fixed position, while near the preheating area, they correspond to the external power supply voltage. The switching is the same as in the embodiment of FIG. 28, and it is performed between the standard operation field and the preheating field. The negative voltage VNN is maintained regardless of the external power supply voltage. In this embodiment, as described above, VCH generates a reference voltage VRP based on VDL, switches the resistance 値 of resistor RL 2 to two stages, and increases the difference voltage between VDL and VDL in the preheating field. In this way, it can be accurate regardless of the standard operation field or preheating field Set the voltage applied to the MO SFET to reduce defective components caused by excessive stress and improve product yield. The above VDL uses the reference voltage VREFO when it is used in the standard operation field, and generates VDL by the same constant voltage circuit as above. In the field of preheating, it is switched to a voltage that depends on the above external power supply voltage to replace the voltage VRE F 0.

The sense amplifier provided in the field of the sense amplifier is constituted by a time-sharing sensing method. In addition to the sense amplifiers arranged at both ends of the memory cell array, the complementary bit lines are arranged around the sense amplifier as the center. It is selectively connected to the complementary bit lines of any one of the left and right memory blocks. As described above, each of the two memory arrays arranged in two groups is arranged in its central part with a main character drive selection circuit MWL and a main character driver. The main character selection circuit MWL is commonly provided corresponding to the two memory arrays centered on it. The main character driver is used to form a selection signal of a main character line extending through the one memory array. In addition, a driver for sub-character selection is also provided in the main character driver, which extends parallel to the main character line as described later to form a selection signal for the sub-character selection line. There are 2 256 sub-character lines (not shown) set in a block of 100 million, and there are 5 1 2 pairs of complementary bit lines (or data lines) orthogonal to it. In a memory array, 16 billion blocks are set in the direction of the bit line, so there are about 8 K sub-word lines in total, and the whole chip is about 16 K points. In a memory array, there are 8 memory blocks on the word line, so there are about 4 K complementary bit lines in the whole. There are four such memory arrays, so all 16 K points of complementary data lines are set, and the total memory capacity is 16KX 1 6K = 2 56M (million) bits.

The sub-character driver is divided into 1/8 lengths relative to the main character line to form a selection signal of the sub-character line extending parallel thereto.

If we focus on one memory cell array, one of the eight sub-array drivers corresponding to one memory block included in the eight memory cell arrays allocated by one main character line corresponds to one of the sub-character drivers. As a result of the sub-character selection line being selected, one of the 8 x 4 = 32 sub-character lines to which a main character belongs is selected. As mentioned above, there are 4 K (4 0 9 6) memory cells in the direction of the main character line, so 4 0 9 6/8 = 5 1 2 memory cells are connected to one auxiliary character line. Although not particularly limited, in a regeneration operation (for example, a self-excitation regeneration mode), eight sub-character lines corresponding to one main character line are set to a selected state. As mentioned above, a memory array has a memory capacity of 4 K bits with respect to the direction of the complementary bit line. However, when a 4 K memory cell is connected to one complementary bit line, the parasitic capacity of the complementary bit line becomes larger, and the readout signal level cannot be obtained due to the capacity ratio of the capacitor to the fine information memory capacitor. , Divided into 16 points relative to the direction of the complementary bit line.

In this embodiment, a P-channel MOSFET is used, and even when the critical threshold voltage of the MO SFET is high, there is sufficient current to flow through the differential amplifier. There is also a push-pull conversion circuit composed of two terminals to drive the P-channel output buffer. The potentials of the bases of the transistors T 3 and T 4 and the voltage between the emitters (a) and (b) are 0.6V to 0.7V, which is relatively low. Therefore, in the circuit of the embodiment of FIG. 17 described above, in MO SF ET with a power supply voltage of 3.3V to 5V, the critical threshold voltage is the same level as the potential of the above nodes (a) and (b), which cannot circulate enough. The current causes deterioration of the power input characteristics or stability. Especially when the power is turned on, the potentials of nodes (a) and (b) are 0V, the differential amplifier cannot operate, and the reference voltage V r e f may not rise. In this embodiment, the lower voltages of the above nodes (a) and (b) are borne by the P-channel MOSFETs MP1 and MP2, so even when the critical threshold voltages of the MOSFETs MP1 and MP2 are set to be high, sufficient power can be ensured. The voltage between the gate and the drain can flow more current, so the characteristics and stability of the power input can be improved. Since the reference voltage V r e f is generated based on the ground potential V S S, it is necessary to connect the base or emitter terminal of the bipolar transistor to the ground potential V S S. In order to operate at low power voltage, P channel type is required:--------.....

Description of the invention (56) Driver of MOSFET. If it is driven by a common P-channel type MO S F E T input current mirror load type amplifier, it will not be able to output a sufficient level and the P-channel type MOS cannot be cut off. Therefore, in this embodiment, in order to solve this problem, a two-terminal push-type conversion circuit is provided to ensure a sufficient level. That is, between the drain of the P-channel MOSFET MP 1 constituting one of the differential amplifiers and the circuit ground potential, an N-channel MOSFET Q80 in the form of a diode is connected to the N-channel type with which it forms a current mirror M0SFETQ81. This MOSFET Q81 is used to drive a P-channel type MOSFET Q82, which is a diode provided on the power supply voltage side. Between the drain of the other P-channel MOS FET MP 2 constituting the differential amplifier and the circuit ground potential, an N-channel MOSFET Q83 in the form of a diode and an N-channel MOSFET in the form of a current mirror are also connected. Q84. The drain of the MOSFET Q84 and the drain of the P-channel MOS FET Q8 5 connected to the P-channel MOSFET Q8 2 to form a current mirror are connected to form a two-terminal push-pull conversion circuit. The push-pull circuit is used to drive the P-channel MOSFET MP3 and the above-mentioned transistors T3 and T4. In addition, the P-channel MOSFET Q87 is often connected to the ground potential of the circuit as a resistance element, and has the function of increasing the potential of nodes (a) and (b) when the power is turned on. Therefore, the ohmic resistance is set For great. In this embodiment, even if the critical threshold voltage of MO S F E T is large, the paper size is applicable to China National Standard (CNS) A4 (210X29 * 7mm)

Description of the invention (57) It can also operate stably from extremely low power voltage β. It also rises quickly when power is turned on and has high stability. FIG. 33 is a circuit diagram of another embodiment of the power supply circuit of the present invention. In this embodiment, the frequency of the oscillation pulse that causes the charge pump circuit to operate is changed in accordance with the load current. To reduce the consumption current, the charge pump circuit can be set to two types: the frequency of the oscillation circuit and the standby mode. However, with this configuration, the maximum current of each mode needs to be used to determine the oscillation frequency. As described above, in a circuit operating with a low power supply voltage, in order to achieve high-speed operation, it is necessary to reduce the critical threshold voltage of MOS F E T. Therefore, when the circuit such as the standby state is not operating, that is, even if the M 0 S F ET in the 0 F F state, a large critical leakage current flows. This current changes exponentially with respect to temperature, so it is necessary to set the oscillation frequency to a higher value, so that the consumption current becomes larger than necessary, which is a problem. In this embodiment, the P-channel type output MOSFET M1 that forms the boosted voltage V CC is connected in parallel with the MOSFET M2 for the P-channel type current detection. A detection current KIL corresponding to the size ratio K of the output MOSFET M1 is formed on the MOSFET M2, and the current K IL flows through the N-channel MOSFET M3 in the form of a diode, and the corresponding voltage signal CFB is supplied to the oscillating circuit. Make the oscillation frequency continuously change. That is, the oscillation circuit is controlled to increase the oscillation frequency in response to an increase in the detection current KIL. Fig. 34 is a circuit diagram of an embodiment of an oscillation circuit used in the circuit of the embodiment of Fig. 33 described above. The oscillating circuit is based on the vertical connection of the inverter circuit to the paper size.

Description of the invention (58) Ring oscillator connected in a ring 'N of the operating current of each inverter circuit The channel-type MOSFETs M5 to M9 are formed in a current mirror form with the N-channel-type MOSFET M3 that detects the above-mentioned current. That is, a signal CFB is supplied to the gates of each of the MOSFETs M5 to M9. The N-channel type MO SFET M4 is converted into a IL current and made to flow through the diode-shaped P-channel type MOSFET M10, and the P-channel type MOSFET Ml 1 ~ Ml 5 which flows the operating current in each converter circuit Set to the current mirror shape, corresponding to the signal CFB to control the delay time of each converter circuit, so that the delay time is changed in inverse proportion to the increase in current to control the oscillation frequency. When the load current IL of the power supply circuit increases, the oscillation The frequency also becomes higher, and the charge pump times per unit time As the number increases, the power supply circuit has a current supply capability corresponding to an increase in load current. At this time, the duty ratio of the oscillating output pulse remains approximately constant, so the efficiency of the charge pump circuit is also approximately constant. Employees' cooperation cooperation of the Central Prototype Bureau of the Ministry of Economic Affairs According to this embodiment, when the critical threshold voltage of the MO SFET becomes lower or when the high-temperature load current increases, the oscillation frequency of the oscillation pulse input to the charge pump circuit also automatically increases, so there will be no insufficient current supply capacity. In addition, the oscillation frequency is automatically lowered at low temperature to reduce the consumption current, so it is very suitable for the power supply circuit mounted on the portable electronic device that requires the consumption current. In the above embodiment, the step-up circuit is taken as an example for specific explanation. However, it can also be applied to a negative charge pump circuit that forms a negative voltage.

Description of the invention (59) Figure 35 is a circuit diagram of one embodiment of the output circuit of the present invention. This embodiment is suitable for a push-pull output circuit which can reduce the leakage current and enhance the driving ability. The circuit of this embodiment is the same as the driving circuit of the sense amplifier of FIG. 1. In order to enhance the driving ability, the N-channel type driving MOSFET M01 and P-channel type driving MOSFET M02 are set to a low threshold voltage. Therefore, in order to reduce the direct current (through current) flowing through the two MOSFETs M01 and M02 caused by the critical leakage current when the MOSFET M01 or M0 2 is in the 0 FF state, level conversion circuits LSN and LSP that form an input signal are provided. , The source and gate between the MOSFETs M01 and M02 supplied in the 0FF state are reverse biased. One level conversion circuit L SN accepts the input signal of V S — VDD and converts it to VDD — VNN level. Based on the VNN output state, VNN is applied between the gate and source of MOSFET M01 — VSS reverse bias.
