Abstract:
According to one embodiment, a semiconductor memory device includes first and second memory cells, a first word line, first and second sense amplifiers, first and second bit lines, a controller. The first and second sense amplifiers each include first and second transistors. The first bit line is connected between the first memory cell and the first transistor. The second bit line is connected between the second memory cell and the second transistor. In the read operation, the controller is configured to apply a kick voltage to the first word line before applying the read voltage to the first word line, and to apply a first voltage to a gate of the first transistor and a second voltage to a gate of the second transistor while applying the kick voltage to the first word line.
