There is provided an information processing apparatus including a region detection unit configured to detect a region that satisfies a predetermined condition among a plurality of regions included in a data storage apparatus, and a refresh processing unit configured to skip refresh with respect to the region that satisfies the predetermined condition when performing refresh processing on the plurality of regions.

Information processing to refresh data stored on a data storage apparatus

There is provided a memory control device including a device driver that executes writing or reading of data to/from a main storage unit and temporary writing or reading of data to/from a cache unit including a plurality of cache blocks, and a control unit that issues an instruction for writing or reading of data of a file system to/from the main storage unit or the cache unit to the device driver. The control unit may notify priority information about a priority for data storage into a logical block to which the cache block is associated to the device driver.

Memory control device, memory device, memory control method, and program

A memory device includes a non-volatile memory which allows data to be written, read, and erased electrically and in which writing and reading are done in units of a page and erasing is done in units of a block including a plurality of pages, and a control section that manages access to the non-volatile memory. The control section performs management of access to the non-volatile memory by performing logical address-physical address translation (logical-physical translation) in translation units (TUs) each being an integer fraction of a size of the block and an integer multiple of a page size.
