For the requirement of the stability in large-capacity data storage, this paper proposes a management method of bad block based on setting up block address mapping table in the interior of FPGA.While operating the NAND Flash , we can take advantage of the mapping tables to shield inherent bad blocks and new produced blocks .The research proved that the method can avoid the operation of bad blocks efficiently and improve the reliability of data shortage greatly.
