Abstract
According to one embodiment, a semiconductor memory device includes a first memory cell, a second memory cell, a first word line electrically coupled to the first memory cell, a second word line electrically coupled to the second memory cell, and a control circuit configured to supply voltages to the first word line and the second word line. In a read, the control circuit applies a first voltage to the first word line and a second voltage to the second word line, applies, after applying the first voltage to the first word line and the second voltage to the second word line, a third voltage lower than the first voltage and the second voltage to the second word line, and applies, after applying the third voltage to the second word line, the third voltage to the first word line.
