Abstract:
According to one embodiment, a memory system includes nonvolatile memory and storage unit storing a translation table indicating, by a predetermined management unit, relationships between logical addresses specified by a host and physical addresses in the nonvolatile memory. A memory system of the embodiment includes a controller that when receiving from the host a delete notification indicating a delete area smaller than the management unit specified by a logical address, write a specified data pattern to an area of the nonvolatile memory having a physical address corresponding to the delete area.
