ABSTRACT:
A dual-port semiconductor memory device having one serial memory cell of a serial access memory provided for a predetermined number of bit line pairs. A transfer gate circuit is provided between the serial memory cell and the predetermined number of bit line pairs so that only one bit line pair is selectively coupled to one serial memory at one time. Access to the dual-port semiconductor memory device is made in n/m stages when there are n bit line pairs and m serial memory cells in the serial access memory.
