Abstract

A semiconductor memory device having a data inverting circuit for selectively inverting an input/outpt data of a sense amplifier in such a way that the charging states of respective memory cells connected to two bit lines in each bit line pair become equal for the same input/output data. A clamp circuit draws the potentials of all of the bit lines to a predetermined potential in response to a clear control signal, whereby the contents of all of the memory cells are cleared at the same time.
