Abstract

PURPOSE:To reduce the current consumption of a decoder circuit by forming this decoder circuit, selecting memory cells in a matrix, of NAND circuit of n-type MOSFET connected in series. CONSTITUTION:Matrix-connected FFs 21... forming memory cells are selected by NAND circuit 37..., and 39... constituting a decoder circuit of series-connected n- type MOSFETs 43, 43', 43''.... In the constitution of those circuits 37..., 39..., an address output is held at a low level only when address bits applied to FETs 43, 43'... are all at high levels, thereby selecting FF21. On the other hand, when one of address bits is at a low level, the address output is held at a high level to set an unselection state, so that gates 37..., and 39... will never consume any current. Therefore, the current consumption of the decoder circuit can be reduced in comparison with the NOR constitution of the decoder circuit.
