PROBLEM TO BE SOLVED: To provide a technique capable of shortening the time of writing data in a semiconductor memory.SOLUTION: A semiconductor memory includes a storage region 6 including a plurality of blocks 60 each of which is the erasure unit. The storage region 6 stores a plurality of pieces of divided data obtained by dividing predetermined data. The plurality of pieces of divided data includes a plurality of pieces of compressed divided data 82 each of which is a piece of compressed divided data. The data quantity of each of the plurality of pieces of compressed divided data 82 is less than or equal to the storage capacity of the block 60.SELECTED DRAWING: Figure 4
