| Zusammenfassung: | According to an embodiment, a semiconductor memory device includes a first memory, a second memory, a switch, and a controller. The switch switches between various states including between a first state and a second state. In the first state, the first memory is connected to a host device that reads data from and writes data to the first memory and the second memory is not connected to the host device. In the second state, the first memory is connected to the second memory and the host device is connected to neither the first memory nor the second memory. The controller directs, upon receiving a movement command from the host device, the switch to switch to the second state to move data between the first memory and the second memory. |
