<p><P>PROBLEM TO BE SOLVED: To acquire a flash memory system which can substantially increase rewritable times of a flash memory by suppressing erasure of data as much as possible, even if a microprocessor does not carry a special program. <P>SOLUTION: The flash memory system comprises a sector determination circuit 13 which detects a sector of unwritten status out of a plurality of sectors (0)-(3) when receiving a write command from a microprocessor 1, and writes data received from the outside in an unwritten status sector when the sector determination circuit 13 detects the sector of unwritten status. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
