Abstract
A memory system which is accessible to a host device includes a volatile memory, a nonvolatile memory, and a memory controller that controls the volatile memory and the nonvolatile memory. The memory controller stores first data, which is stored in the volatile memory, in the nonvolatile memory, each time the memory controller stores second data, which is stored in the volatile memory, in the nonvolatile memory. The first data indicates a logical address and a deletion range designated by a deletion request received from the host device, and the second data is designated by a write request received from the host device.
