Non-volatile memory device, non-volatile memory control device, and non-volatile memory control method

A non-volatile memory control device comprising:

• a controller configured to control processing of writing data to a non-volatile memory,
• wherein the controller is configured to:
• receive a write request from a host device that manages allocation of a write region,
• receive first information indicating whether the data is an object of a write of sequential management from the host device,
• perform first write processing in which the data is sequentially written when the data is the object of the write of the sequential management,
• perform second write processing in which the data is written when the data is not the object of the write of the sequential management, the second write processing being different from the first write processing, and
• receive second information from the host device, the second information indicating a method of reading data from the write region.
