Abstract
A semiconductor memory device includes a stacked body in which conductive layers are stacked with an insulating layer interposed therebetween, a semiconductor film to provide a channel for a plurality of memory cell transistors having gates electrically connected to the conductive layers of the stacked body, respectively, an insulating film extending in the stacking direction between the conductive layers and the semiconductor film, and a control circuit configured to control a program voltage to be applied to a conductive layer electrically connected to a memory cell transistor that is a target of a write operation, and a transfer voltage to be applied to conductive layers electrically connected to other memory cell transistors that are not the target of the write operation, wherein the control circuit is configured to vary the transfer voltage to be applied depending on a number of bits that are being written in the write operation.
