Abstract
According to one embodiment, a semiconductor memory device includes: a first memory cell including a first variable resistance element; a first buffer coupled to the first memory cell; a second memory cell including a second variable resistance element; and a second buffer coupled to the second memory cell. In data write, first data is stored in the first buffer and is transferred to the first memory cell, and second data is stored in the second buffer and is transferred to the second memory cell, and a start of the transferring the first data and the second data is based on a first data transfer signal.
