Abstract

See full text

In a non-volatile semiconductor storage, at the time of a data writing, the size of the data to be written is compared with the size of an erase block and/or the size of a writable storage unit in the erase block. The data having the size corresponding to the size of the erase block is written into a writable erase block, and the data having the size smaller than the size of the erase block is written into the writable storage unit(s), so that a storing area optimum to the size of the data to be written is allocated.
