Abstract
A semiconductor memory device in which the selected word line is energized only during a limited period of time is disclosed. The memory device is equipped with a clock generator which generates a one-shot pulse signal in response to a change in address signal or to an application of a write-enable signal, and the selected word line is energized by the one-shot clock signal. The clock generator further generates a one-shot clock signal in response to a change in an input data signal in a data-write operation. The input data is thereby sorted into the accessed memory cell, even when the data to be stored is supplied a relatively long time after the write-enable signal is applied.
