Abstract
Different block management values that sequentially increase are set for a plurality of blocks to indicate active states of the blocks. For example, a first block management value “$1111” is stored in a first block, and a second management value “$1112” is stored in a second block. Thus, even when more than one block is in an active state, an updated value is read from the block that stores a larger block management value. This allows for the true updated value to be read.
