Abstract
According to one embodiment, a semiconductor memory device includes: a first bit line; a first memory cell electrically coupled to the first bit line; and a first sense amplifier configured to sense and store data read out to the first bit line. The first sense amplifier includes a first latch circuit and a second latch circuit. In a program operation, each of the first and second latch circuits stores any one bit of program data. In a first verify operation, data is exchanged between the first latch circuit and the second latch circuit when performing the first verify operation for a first data.
