DDR SDRAM (English：Double Data Rate Synchronous Dynamic Random Access
Memory, double synchronization of data streams dynamic RAM),.DDR SDRAM are improved on the basis of original SDRAM.
Core frequency, clock frequency and the data transmission frequencies of DDR：
Core frequency is exactly the working frequency of memory；The core frequency of DDR1 memories is identical with clock frequency, is arrived
Just there are the concept of clock frequency, a frequency for exactly obtaining core frequency by frequency doubling technology during DDR2 and DDR3.Number
It is exactly to transmit the frequency of data according to transmission frequency.DDR1 pre-read is 2, and DDR2 pre-read is 4, and DDR3 pre-read is 8.
DDR1 when data are transmitted in rising edge and trailing edge all transmission primarieses of clock pulses, so data transmission
Frequency is exactly 2 times of core frequency.DDR2 memories are by 2 times of core frequency frequency multiplication so clock frequency is exactly 2 times of core frequency
, similary or rising edge and each transmission primaries data of trailing edge, so data transmission frequencies are exactly 4 times of core frequency.
The clock frequency of DDR3 memories is 4 times of core frequency, so data transmission frequencies are exactly 8 times of core frequency
.
Refering to Fig. 1, Fig. 1 is the sequence diagram of DDR, as shown in Figure 1, having can be found that more than it two signals from Fig. 1：CLK#
(differential clock signal) and DQS (data decimation pulse), CLK# are with normal CLK clock phases on the contrary, forming differential clock signal.
And the transmission of data carries out in the crosspoint of CLK and CLK#, it is seen that in the rise and fall of CLK along (being exactly CLK# at this time
Rising edge) there are data to be triggered, so as to fulfill DDR.Here, we can say that achieved the purpose that DDR by differential signal,
Even CLK# has helped the triggering of second data.
Refering to Fig. 2, Fig. 2 is a kind of anti-interference method for electronic device that the application provides, and this method is by being equipped with DDR's
Electronic device performs, which can specifically include：Smart mobile phone, tablet computer, palm PC, laptop, shifting
One kind in dynamic internet device or Wearable, this method is as shown in Fig. 2, include the following steps：
Step S201, electronic device obtains the first frequency spectrum where Current wireless communication channel；
Radio communication channel in above-mentioned steps S201 is specifically as follows：GPS communication channel, wifi communication channels or GSM
One kind or any combination in communication channel.The first frequency spectrum is determined according to the communication channel, for example, the frequency spectrum of GPS communication channel
Can be：1575.42MHz；The frequency spectrum of wifi communication channels can be：2.4GHz, the frequency spectrum of gsm communication channel can be：
【885MHz,960MHz】, the specific channel channel different according to its is in interior value difference.
When radio communication channel is gsm communication channel, the specific method of electronic device can be in above-mentioned steps S201,
For caller process, corresponding flow chart as shown in Figure 2 a, as shown in Figure 2 a, includes the following steps：
Step S201a, electronic device can be to base station sendaisle demand, concrete implementation mode, electronic device to
Base station sends a short random access burst.
Step S202a, base station is in broadcast channel (English：Broadcast channel, referred to as：BCH it is electronic device on)
Specify an independent dedicated channel (English：Independent dedicated channel, referred to as：SDCCH).
Step S203a, electronic device communicates with base station on SDCCH.
Step S204a, electronic device and base station carry out purview certification.
Step S205a, after purview certification success, base station sends the Traffic Channel a specified (English to mobile phone：
Trade channel, referred to as：TCH).
Step S206a, electronic device carries out voice data transmission by TCH and base station.
For called flow, flow as shown in Figure 2 b,
Step S201b, base station is in paging channel (English：Paging channel, referred to as：PCH) call and used on passage
IMSI number calling called terminal in SIM；
Step S202b, called terminal is sent out in random access channel (Random Access Channel, RACH) to base station
Send access request；
Step S203b, BCH is specified in base station to called terminal；
Step S204b, called terminal communicates with base station on SDCCH.

Step S206b, after purview certification success, base station sends a service signal specified to called terminal.
Step S207b, called terminal carries out voice data transmission by TCH and base station.
Step S202, the first current electronic device extraction DDR working frequency, the first working frequency of detection and first frequency
Whether spectrum is disturbed.
Whether the first working frequency of detection in above-mentioned steps S202 disturbs concrete implementation method can with first frequency spectrum
Think any one in following manner：
Mode A, whether first working frequency is judged with the first spectrum overlapping or partly overlapping, specifically, the i.e. core of DDR
Whether frequency of heart is located in the range of the first frequency spectrum, in the range of belonging to the first frequency spectrum such as core frequency, determines the first work frequency
Rate and the first spectrum overlapping, determine the first working frequency and first spectral interference.
Mode B, whether the frequency multiplication of first working frequency is judged with the first spectrum overlapping or partly overlapping, specifically, i.e.
Whether the frequency multiplication of the core frequency of DDR is located in the range of the first frequency spectrum, as the frequency multiplication of the core frequency of DDR belongs to first frequency
In the range of, it determines the first working frequency and the first spectrum overlapping, determines first working frequency and first spectral interference.
Step S203, when electronic device determines first working frequency with first spectral interference, by the working frequency of DDR
It adjusts to the second working frequency.
First frequency spectrum of the technical solution that the application provides where Current wireless communication channel is determined, extracts the of DDR
One working frequency, judges whether first frequency spectrum disturbs with the first working frequency, such as generates interference, by the first work frequency of DDR
Rate is adjusted to the second working frequency and the first working frequency of DDR is avoided to generate interference to first frequency spectrum, improves communication channel
Quality improves user experience.
Optionally, the above method can also include after step S203：
Electronic device obtains the second frequency spectrum where Current wireless communication channel again, judges second frequency spectrum and the first work
Whether working frequency disturbs, and when not disturbed with first working frequency such as second frequency spectrum, the working frequency of DDR is adjusted back first
Working frequency.
Above-mentioned technical proposal is not when the second frequency spectrum where radio communication channel and the first working frequency disturb, by DDR
Working frequency adjust back the first working frequency, such DDR can work again in the first working frequency, because for DDR cores
For frequency, although it can be adjusted, such as overclocking or low frequency adjustment, have after adjusting DDR core frequencies to the resource of DDR
Corresponding loss, short-term second working frequency that is operated in is still able to what is received for electronic device, if permanent worker
Make the second working frequency can strong influence DDR work efficiency, then when the second frequency where radio communication channel with
When first working frequency is not disturbed, it is just very necessary to adjust back the first working frequency, can either so avoid disturbing, nor affect on
The work efficiency of DDR.
Optionally, the above method can also include：
Determine the digital independent state of electronic device, as the electronic device digital independent state for no data read and
When data write, current time t0 is recorded, detects the digital independent state of the electronic device to read the time for obtaining write state
The differential clocks of DDR and clock signal are all provided with being set to low level by t1 within the time cycle of t0 and t1.
This technical solution is not when definite electronic device has corresponding digital independent, by the differential clocks and clock
Signal, which is arranged to low level, can so close the working frequency of DDR, and the working frequency of such DDR i.e. will not be to current channel radio
Believe that channel generates interference, so as to improve communication quality within the time cycle of t0 and t1.
Differential clocks, which are that one of DDR is necessary, to be designed, but the effect of CLK#, can not be interpreted as second triggering clock,
But play the role of triggering clock alignment.Since data are the upper lower edge triggerings in CLK, transmission cycle is caused to shorten one
Half, it is therefore necessary to ensure the stabilization of transmission cycle to ensure the correct transmission of data, this requires CLK it is upper it is lower will along spacing
It is accurately controlled.But because the reasons such as change of temperature, resistive performance, may change under CLK is upper along spacing, at this time with
The CLK# of its reverse phase just plays the role of correction (CLK is slowed down under rising soon, and CLK# is then that the slow decline of rising is fast).And due to upper and lower
Along the reason for triggering, also make it possible CL=1.5 and 2.5.It ensure that the accuracy of trigger timing with the CLK# of CLK reverse phases.
And for CLK# and CLK, the core frequency of DDR can be closed by the low and high level for controlling CLK# and CLK.
DQS is the critical function in DDR SDRAM, its function is mainly used to accurately distinguish within a clock cycle
Go out each transmission cycle, and data are accurately received convenient for recipient.For each chips all there are one DQS signal line, it is two-way
, in write-in, it is used for transmitting the DQS signal sent by north bridge, during reading, then generates DQS from chip and is sent to north bridge.It is complete
Entirely it can be said that it is exactly the synchronizing signal of data.
When reading, DQS is generated in (and in crosspoint of CLK and CLK#) simultaneously with data-signal.And in DDR memories
CL namely from CAS be issued to DQS generation interval, data really appear in data I/O buses compared with DQS triggering when
Between interval be referred to as tAC.Note that this and the t in SDRAMACDifference.In fact, when DQS is generated, chip internal prefetches
Through finishing, tACRefer to the data output time of grey parts in structure chart above, due to prefetching, actual data pass
Go out to shift to an earlier date and occur (data are spread out of in advance in DQS) in DQS.Due to being parallel transmission, DDR memories are to tACAlso have certain
It is required that for DDR266, tACAllowed band be ± 0.75ns, be then ± 0.7ns, in relation to their sequential for DDR333
Diagram sees above, and the introduction period of one section of DQS is contained in wherein CL.
DQS be in order to ensure the selection data of recipient, DQS when reading with data synchronous transfer, if with the upper of DQS
The danger that lower edge distinguishes the data cycle is very big.Since chip has the operation prefetched, so synchronization during output is difficult control, it can only
It is limited in the range of the regular hour, the possible faster or slower of time of occurrence of the data in each I/O ports can have certain with DQS
Interval, why this namely will be there are one tACThe reason for regulation.And in recipient, all must assure that synchronous reception, it is impossible to
There is tACEtc deviation.So in write-in, chip no longer oneself generation DQS, and on the basis of the DQS that sender is transmitted, and
The regular hour accordingly is delayed, (cut-point is exactly upper and lower when reading for the selection cut-point in data cycle at the middle part of DQS
Edge), two transmission cycles are separated from here.The advantage of doing so is that due to all meetings of each data-signal, there are one logic levels
Hold period, even if asynchronous when sending, under on DQS along when all in hold period, the standard of data receiver triggering at this time
True property is undoubtedly highest.In write-in, using the interim portion of high/low level of DQS as data period divisions point rather than up/down
Edge, but the reception triggering of data is still the up/down edge of DQS.
Write-in delay, it can be found that write latency is not 0, is write in DQS write timing figures above sending
After entering order, DQS will wait a period of time that can just be sent to write-in data.This cycle is referred to as DQS compared with writing commands
Time delay.
Time delay is an important parameter of DDR memory write operations, probably receive if too short it is wrong, it is too long then
Cause bus free.Time delay is most short cannot to be less than 0.75 clock cycle, most long no more than 1.25 clock cycle.Have
People may say, if so, DQS is not just asynchronous with the clock in chipRight, under normal circumstances, time delay is
One clock cycle, but the clock of reciever is only used for the synchronization of control command signal during write-in, and the receiving of data is then complete
It is synchronized by DQS, so DQS is asynchronous with clock also, it doesn't matter.But, time delay generates a unfavorable shadow
Ringing --- the increase of writeafterread operating delay if CL=2.5, will also add in half of clock cycle on the basis of time delay,
Because order will be sent in the rising edge of CLK.
In DDR SDRAM, burst-length only has 2,4,8 three kind of selection, without random-access operation (burst-length
1) to happen suddenly with full page formula.Why this isBecause L-Bank once just accesses the data of twice chip bit wide, core
Piece at least will also be transmitted twice just can be with otherwise how internal additional data are handledAnd the true card of full page formula burst
Bright is difficult that can use in PC memory.
But defining for burst-length is also different with SDRAM, it no longer refers to the number of memory cells continuously addressed
Amount, and refer to continuous transmission cycle number, it is the data of a chip bit wide every time.It is write for burst, if wherein had not
Think the data of deposit, can still be shielded with DM signals.DM signals and data-signal are simultaneously emitted by, and recipient is DQS's
Rise and fall are along the state of DM is judged, if DM is high level before, then the data chosen in the middle part of DQS are just shielded
.Someone may think that DM is input signal.
DDR SDRAM have the accuracy of clock a very high requirement, and DDR SDRAM are there are two clock, and one is outer
The bus clock in portion, one is internal work clock, the two clocks of DDR SDRAM in theory should be synchronous, but
For various reasons, as temperature, voltage fluctuation and generating delay both makes to be difficult synchronous, still more clock frequency also has not in itself
Stable situation (SDRAM also internal clockings, but because its work/transmission frequency is relatively low, inside and outside stationary problem is not
It is prominent).The t of DDR SDRAMACExactly because internal clocking and external clock have caused by deviation, it is likely to cause factor
The disastrous effect of mistake is generated according to asynchronous.In fact, asynchronous is exactly a kind of positive/negative delay, if delay is inevitable, then
If one length of delay of setting, such as a clock cycle, then the rise and fall of interior external clock along or it is synchronous.It is in view of outer
Portion's clock cycle will not definitely be unified, thus need according to the delay of external clock dynamic corrections internal clocking come realize with outside
The synchronization of portion's clock, here it is the tasks of DLL.
DLL is different from the PLL on mainboard, it is not related to frequency and voltage conversion, but generates a retardation to inside
Clock.For DLL there are two types of implementation method, one is clock frequency mensuration (CFM, Clock Frequency at present
Measurement), one is clock comparison method (CC, Clock Comparator).
CFM is the frequency cycle for measuring external clock, then controls internal clocking by length of delay of this cycle, so inside and outside
Clock has just just differed a clock cycle, so as to fulfill synchronization.DLL repeated measurement repetitive control length of delays like this, make
Internal clocking is synchronous with external clock holding.
