摘要： In a semiconductor storage device, a memory controller divides each of blocks in each of chips into a first page set composed of pages and a second page set composed of pages, divides a logical address space into groups, and divides each group into lines. Block units are created each of which is obtained by assembling a predetermined number of blocks from the blocks in each chip. A predetermined number of block units from the block units are managed as standard block units, and the other block units are managed as spare block units. Each standard block unit is made to correspond to one group. The corresponding group data is stored in the pages in the first page set in each block constituting the standard block unit, and unwritten pages for recording update data for the group data are provided to be included in the second page set.

摘要： In a semiconductor memory computer equipped with a flash memory, use of backed-up data is enabled. The semiconductor memory computer includes an address conversion table for detecting physical addresses of at least two pages storing data by designating a logical address from one of logical addresses to be designated by a reading request. The semiconductor memory computer includes a page status register for detecting one page status allocated to each page, and page statuses to be detected include the at least following four statuses: (1) a latest data storage status, (2) a not latest data storage status, (3) an invalid data storage status, and (4) an unwritten status. By using the address conversion table and the page status register, at least two data s (latest data and past data) can be read for one designated logical address from a host computer.
