According to one embodiment, a semiconductor memory device includes a memory cell array including memory cells, each of which is arranged at a position of between a word line and a bit line, a row decoder, and a bit line control circuit. And when data is to be read out from the memory cell, a charge control circuit controls the gate voltages of a first transistor, a second transistor, a third transistor, and a fourth transistor, respectively, so that the bit line is charged in accordance with a first characteristic obtained by increasing a current driving capacity of the first transistor during a desired period after start of charge of the bit line, and the bit line is then charged in accordance with a second characteristic obtained by returning the current driving capacity of the first transistor to the lower current driving capacity after elapse of the desired period. |
