Abstract
According to one embodiment, a semiconductor memory device includes a memory cell, a word line, a bit line, a first transistor, a second transistor and a driver. The word line is electrically coupled to a gate of the memory cell. The bit line is electrically coupled to one end of the memory cell. The first transistor includes a first gate electrically coupled to the bit line. The second transistor is coupled to a first end of the first transistor. The driver is configured to apply a voltage to the first gate of the first transistor. In a read operation, the driver varies a voltage to be applied to the first gate of the first transistor based on a read voltage applied to the word line.
