<p>PROBLEM TO BE SOLVED: To provide a method for managing data storage flash memory dispensing with the need for having a management area and capable of reducing an access load.SOLUTION: Provided is a method for managing data storage flash memory for storing k parameters (k is a positive integer) that change with time in flash memory that includes j blocks in which units memory is erased (j is an even number equal to or greater than 2), the flash memory being configured as stated below. Each of the j blocks is divided into two areas, each comprising j/2 blocks, which are defined as a primary macro block and a secondary macro block. Each of the primary macro block and the secondary macro block is provided with k or more segments, each having equal storage capacity, some of which is made active and the other is made standing by. Each of the k parameters is corresponded 1:1 to k segments among the k or more segments, and is written to a corresponding segment in the active macro block and read out from that segment.</p> |
