ABSTRACT:
A static random access memory device capable of preventing stability issues during a write operation is provided, in which a memory cell is coupled to a read word line, a write word line, a read bit line, a write bit line and a complementary write bit line, and a multiplexing unit is coupled to the read bit line, the write bit line and the complementary write bit line. The multiplexing unit applies first and second logic voltages representing a logic state stored in the memory cell to the write bit line and the complementary write bit line, respectively, when the memory cell is not selected to be written by an input signal from a data driver and the read word line is activated, in which the first and second logic voltages are opposite to each other.
