Abstract
A semiconductor memory device includes memory cell strings including selection transistors and memory cells coupled between the selection transistors, a peripheral circuit configured to apply an operating voltage to the memory cell strings during a read operation or a verify operation, and a control circuit configured to control the peripheral circuit so that the operating voltage being applied to the selection transistors is controlled to reduce a potential level of a channel of the memory cell strings during the read operation or the verify operation.
