DATA MANAGEMENT SYSTEM FOR NON-VOLATILE MEMORY, DATA MANAGEMENT METHOD FOR NON-VOLATILE MEMORY, AND ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To materialize the long service life of a non-volatile memory by increasing effective capacity on the non-volatile memory and by restraining useless data erasing processing to the non-volatile memory (namely, each erasure block) in a data management system for the non-volatile memory. SOLUTION: The data management system for the non-volatile memory comprises: a data storage region generation means generating a data storage region (a) having the same size as the data size of data stored on the erasure block (physical block) of the non-volatile memory X; a data management information storage region generation means generating a data management information storage region b storing data management information representing specified information on the data on the erasing block; a data storage means storing the data on the data storage region (a); and a data management information storage means storing the data management information on the data management information storage region b in accordance with the storage processing of the data by the data storage means.
