Title: Memory circuit
Inventor: MASUKO KOICHIRO
IPC: G11C11/34
Filed: 1987-04-24
Abstract: PURPOSE:To reduce the power consumption by selecting only a part of plural subarrays of memory cells and activating only a Y decoder attending upon the selected subarray. CONSTITUTION:Only sense refresh amplifiers SAa and SAb attending upon a selected subarray are activated. Meanwhile, the AND signal between an X address signal Xn and an essential Y address signal is used as the Y address signal applied to Y decoders YD1a and YD2a, and the AND signal between an X address signal the inverse of XN and the essential Y address signal is used as the Y address signal applied to Y decoders YD1b and YD2b. Thus, X address signals XN and the inverse of XN applied to an input/output control circuit IOC are unnecessary to facilitate designing the circuit IOC, and the power consumption of the Y decoder part is reduced to a value obtained by dividing the conventional power consumption by the division number of subarrays.
