A semiconductor memory device according to an embodiment includes a string, a bit line, a well line, and a sequencer. The string includes first and second select transistors, and memory cell transistors using a ferroelectric material. The bit line and the well line are connected to the first and second select transistors, respectively. At a time in an erase verify operation, the sequencer is configured to apply a first voltage to the memory cell transistors, to apply a second voltage lower than the first voltage to the first select transistor, to apply a third voltage lower than the first voltage to the second select transistor, to apply a fourth voltage to the bit line, and to apply a fifth voltage higher than the fourth voltage to the well line.
