<P>PROBLEM TO BE SOLVED: To reduce the time required for writing data, while handling memory corruption. <P>SOLUTION: A physical block number of all updating blocks in a data area is referred to be recognized as updating blocks in the data area, in step S34. All the updating blocks recognized as the updating blocks in the data area are erased all together in step S35. Processing time is shortened as compared with the case where the data is erased every time the data are written in the physical block. The present invention is applicable when writing the data into a recording medium, such as an EEPROM, where the data recorded in a recording area cannot be overwritten, and the new data are recorded after erasing the data already recorded. <P>COPYRIGHT: (C)2011,JPO&INPIT |
