description PROBLEM TO BE SOLVED: To provide a technology for recording data in a flash memory, capable of further reducing the possibility of losing the stored data.SOLUTION: When data in a block 1 is erased, a block ID of a block 2 where the latest value of the data is stored is written in a management block, and then the data in the block 1 is erased. After a control device is recovered from reset, if there are two blocks having a block status that the block is in use, among the two blocks, data of the block (block 1) which is different from the block (block 2) having the block ID written in the management block is erased.
