Abstract
According to one embodiment, a semiconductor memory device includes a plurality of stacked first chips and a second chip. The second chip outputs a first signal to the first chips. The first chip outputs status information at timing based on the received first signal. The first chip shifts the received first signal and outputs the shifted first signal to the first chip of a next stage in synchronization with the first clock signal. The second chip receives a plurality of status information output in a serial manner from the first chips.
