Abstract
A semiconductor memory device is provided. The semiconductor memory device includes memory strings including drain-side memory cells connected between a bit line and a pipe transistor, and source-side memory cells connected between the pipe transistor and a source line, and a peripheral circuit suitable for applying a pipe gate voltage to a pipe gate of the pipe transistor before applying pass voltages to turn on non-selected memory cells among the drain-side memory cells and the source-side memory cells during a read operation.
