Abstract
Aiming at the request of mass data storage about NAND Flash, this paper proposes a management method with bad block based on setting up RAM to store effective block address in FPGA. In the system of mass data storage,next effective block address is determined and stored in built register,according to calling testing effective block address function. When operating NAND Flash, the contents of register are constantly updated and read so that bad blocks can be managed. Tests show that this method can greatly reduce the size of register and save FPGA resources. Through the management of bad blocks, you can make the reliability of data storage greatly improved.关键词
