ABSTRACT:
This invention provides static random access memory (SRAM). The SRAM has a plurality of memory cells arranged in row and column directions. The plurality of memory cells each have a latch circuit in which input and output terminals of a pair of inverters are cross-connected and which maintains complementary levels at a pair of storage nodes, and a pair of write transistors provided between the pair of storage nodes and a prescribed power supply voltage. Further, the gate potentials of the pair of write transistors are respectively controlled according to a row address, a column address, and write data.
