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.
