Abstract
According to an embodiment, a semiconductor memory device includes a first chip, a second chip, and a third chip. In a case where a first command sequence including a first address indicating the first chip is received from the first device, the third chip performs transfer of a second command sequence including the first address via the first channel and transfer of a third command sequence including a second address indicating the second chip via the second channel. After a first time elapses from completion of the transfers of the second and third command sequences, the third chip transfers first read enable signals to the first and second channels in parallel, and acquires pieces of first status information in parallel via the first and second channels. The third chip outputs first status information to the first device.
