Abstract
A non-volatile memory device includes a non-volatile memory unit, a control unit, and an interface. The control unit receives a write request, determines whether data is an object of a write of sequential management when a write size of the received data is smaller than a management unit of erasure, performs first write processing in which the received data smaller than the management unit of the erasure is sequentially written when the data is the object of the write of the sequential management, and performs second write processing in which the received data smaller than the management unit of the erasure is written by the management unit of the write when the data is not the object of the write of the sequential management.
