The nonvolatile memory includes a first memory cell configured to nonvolatilely store data of a plurality of bits including a first bit and a second bit, and a second memory cell configured to nonvolatilely store data of at least one bit. The memory controller is configured to execute a save operation in accordance with reception of a command from a host, in the save operation, write first bit data to the second memory cell in a case where the first memory cell stores the first bit data as the first bit and does not store data as the second bit, and transmit, to the host, a completion response to the command after the first bit data has been written to the second memory cell.
