Abstract

The semiconductor memory device includes a memory cell array that includes a plurality of cell strings coupled between a common source line and a plurality of bit lines, a peripheral circuit that reads data stored in a selected memory cell, a bouncing detection circuit that compares a voltage supplied to the common source line and a reference voltage to thereby output a detection signal while performing a reading operation, and a control circuit that controls the peripheral circuit in order to perform the reading operation by adjusting the number of sensing operation times in accordance with the detection signal.
