Abstract

A high performance semiconductor memory read/write data access circuit including a sense amplifier directly coupled to a pair of bit lines is provided with a pair of bit switching devices to enable data communication external to the memory. Control potentials and timing of switching signals are provided in such a manner that only one of the bit switches becomes conductive during reading and writing access to the memory.
