Abstract
A semiconductor memory device includes a memory cell array, a read/write control circuit, a signal generator, and a write error prevention circuit. In the memory cell array, a plurality of memory cells are formed at intersections of pluralities of word lines and bit lines. The read/write control circuit controls a data read/write from/in the memory cell array in accordance with a mode setting signal representing a read/write mode, a data input signal, and an address signal. The signal generator generates a one-shot pulse signal when the mode setting signal represents a write mode. The write error prevention circuit precharges a bit line of the memory cell array by the one-shot pulse signal from the signal generator.
