Abstract
In a semiconductor memory device of the present invention, data read from a memory cell to a pair of complementary data lines or a pair of common data lines are fed directly to an output circuit not through any sense amplifier. As a result, the delay time of the sense amplifier itself is omitted from the address access time of the conventional semiconductor memory device using the sense amplifier, so that the semi-conductor memory device of the present invention can have its address access time made shorter than that of the conventional semiconductor memory device.
