Abstract
A semiconductor memory device is provided including plural memory cells and capable of a dual port access. In the memory device the memory cell is composed with two driver transistors , two load transistors , and two access transistors , and in the data read, the word line makes the access transistors conductive to read out data held in the driver transistors to a pair of the bit lines, and in the data write, the load transistor control line makes the load transistors conductive to write data into the driver transistors from a pair of the memory cell VCC lines.
