Abstract
A high capacity NAND Flash memory storage system with open system architecture is proposed in this article,include design of hardware system and software system,and the management of storage of NAND Flash is described in particular in software system,achieving the purpose of bad block management and wear leveling by two steps of address map,recycling dirty block according to the number of dirty page and transfer the static information according to the time mark. This design could provide all kinds of storage device with NAND Flash storage system,and could storage data easily and quickly without regard to the physical character of NAND Flash.
