Abstract
According to an embodiment, a semiconductor memory device includes a first chip, a second chip, and a third chip. The third chip is connected to the first chip via a first channel and connected to the second chip via a second channel. Upon receiving a first command sequence for data transfer from a first device, the third chip transfers a second command sequence for the data transfer to the first chip via the first channel and transfers a third command sequence for the data transfer to the second chip via the second channel. The first address includes a chip identification number of a value indicating the first chip. The second command sequence includes the first address. The third command sequence includes a second address obtained by replacing the value of the chip identification number in the first address indicating the first chip to a value indicating the second chip.
