ABSTRACT:
A semiconductor memory device in which dual ports are provided for selecting a specific memory cell from a memory cell matrix includes a driving state detection unit for detecting the state of driving word lines of the two ports and delivering a detection signal based on the detection, where one of the ports is in the writing state with regard to the memory cell, and a bit line short-circuiting unit responsive to the detection signal from the driving state detection unit for realizing a short-circuit between predetermined bit lines.
