Memory system

Abstract

According to one embodiment, a memory system is connectable to a host including a first memory. The memory system includes a non-volatile second memory, a volatile third memory, and a controller. The controller uses the third memory as a work memory, and executes data transfer between the host and the second memory. The controller receives a first command to change a power mode from the host. The controller transfers first data to the first memory and transfers second data to the second memory in response to the receipt of the first command. The controller transmits a response of completion of data transfer. The first data and the second data are included in third data. The third data is data in the third memory.

Dependencies are inferred from the claim text.
