MEMORY DEVICE AND NON-TRANSITORY COMPUTER READABLE RECORDING MEDIUM

摘要

According to one embodiment, a memory device includes a nonvolatile memory, address translation unit, generation unit, and reception unit. The nonvolatile memory includes erase unit areas. Each of the erase unit areas includes write unit areas. The address translation unit generates address translation information relating a logical address of write data written to the nonvolatile memory to a physical address indicative of a write position of the write data in the nonvolatile memory. The generation unit generates valid/invalid information indicating whether data written to the erase unit areas is valid data or invalid data. The reception unit receives deletion information including a logical address indicative of data to be deleted in the erase unit area.
