Abstract
When a write command is issued, new data is written into a free physical block of a nonvolatile memory (). Here, if data of the same logical block has been written already, the block is erased and a recording state is judged by a recording state judgment unit (). A physical block is swapped according to the number of write processes performed. Thus, it is possible to effectively perform a swap without increasing the number of write processes in a particular area, thereby increasing the lifetime of a nonvolatile storage module.
