Abstract
A static random access memory ('SRAM') is provided which includes a plurality of SRAM cells arranged in an array having a plurality of portions. The SRAM includes a plurality of voltage control circuits corresponding to respective ones of the plurality of portions of the array. Each of the plurality of voltage control circuits is coupled to an output of a power supply, each voltage control circuit having a function to temporarily reduce a voltage provided to power supply inputs of a plurality of SRAM cells that belong to a selected one of the plurality of portions of the SRAM. The power supply voltage to the selected portion is reduced during a write operation in which a bit is written to one of the SRAM cells belonging to the selected portion.
