According to one embodiment, a memory device includes a first memory, a control circuit controlling the first memory, and a second memory storing a second program. The second program manages management information associated with the first memory, sends the management information conforming to a specific interface to a first program if a command conforming to the specific interface is an output command to output the management information. The second program receives first information conforming to the specific interface and issued by the first program, translates the first information into second information corresponding to the second program, translates the second information into third information corresponding to the control circuit, and executes processing for the first memory in accordance with the third information.
