摘　　要：完成了一种基于NAND Flash存储介质的开放式大容量数据存储系统设计,包括硬件系统以及软件系统的设计,并在软件设计中重点提出了应用于NAND闪存的数据管理算法,通过二级地址映射,按块中的脏页数回收脏块和按时间标记转移静态信息实现坏块管理,均匀损耗.该设计能为各种存储器件提供底层的NAND闪存存储系统,使其能方便快速地存储数据而不需要考虑NAND闪存的物理特性.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.

关 键 词：NAND FLASH 存储系统 坏块管理 均匀损耗
