Abstract
According to one embodiment, a memory system includes a nonvolatile memory and a controller. The controller receives a movement request from a host, the movement request designating a logical address of movement target data. When update data corresponding to the designated logical address is not written to the nonvolatile memory by a write request from the host in a period from the reception of the movement request to start of movement of data corresponding to the designated logical address, the controller executes a movement process of moving data corresponding to the designated logical address to a movement destination block in the nonvolatile memory. When the update data is written to the nonvolatile memory in the period, the controller does not execute the movement process.
