According to one embodiment, a memory device includes a nonvolatile semiconductor memory having physical storage areas that includes a user area externally accessible and are divided into management units and a control unit. The control unit receives a control command having a first argument to designate a sequential write area and a read command or a write command, assigns a management unit represented by an address of the read command or the write command as the sequential write...
More DescriptionAccording to one embodiment, a memory device includes a nonvolatile semiconductor memory having physical storage areas that includes a user area externally accessible and are divided into management units and a control unit. The control unit receives a control command having a first argument to designate a sequential write area and a read command or a write command, assigns a management unit represented by an address of the read command or the write command as the sequential write area, and changes memory access control by judging whether an address of a memory access command to access the user area indicates access in the sequential write area whose size is equivalent to the management unit.
