More Information
Summary:A management device according to an embodiment manages reading and writing of data, by a processing circuit, from and into a first memory unit and a non-volatile memory unit containing a plurality of pages, and includes a setting storage unit, an access processing circuit, and a management circuit. The setting storage unit stores an access method indicating whether first access processing of writing and reading data into and from data transferred to the first memory unit from the non-volatile memory unit or second access processing of directly writing and reading data into and from data stored in the non-volatile memory unit is executed for each of the pages. The management circuit changes the access method for a third page on which the second access processing is set to be performed to the first access processing when quality of the third page is equal to or lower than a reference value.
