ABSTRACT:
The invention provides a static random access memory wherein the peak value of current flow therethrough upon flash-clearing is minimized. The static random access memory comprises a memory cell array which is divided into a plurality of memory cell groups which are driven at mutually different timings for flash-clearing by means of a plurality of delay circuits connected in cascade to which the flash-clearing signal is applied.
