摘　　要：Nand Flash因其体积小、容量大、成本低、掉电数据不丢失等一系列优点已经在嵌入式系统中得以广泛应用,然而,由于Flash读写存储的编程特点以及其生产工艺与使用过程中坏块不可避免的问题,有必要对其进行存储过程管理,以使整个系统性能得以改善。本文介绍以K9F6408U0C为代表的Nand flash的存储管理及基于磨损均衡思想的存储管理算法在DSPTMS320F28x的系统中的程序实现。Nand Flash, as a kind of nonvolatile memory, are being widely used in embedded system nowadays due to its＇ advantages of small size, large capacity, low cost etc. It is essential to manage the storage process to improve the performance of the whole system, because of the problems resulting by the reading and writing characteristic, production technics of flash memory, and inevitable bad blocks during its＇operating process. This paper presented the storage management of K9F6408UOC, a representative of Nand Flash, and the program realization of storage management algorithm which is based on wear-leveling idea in DSP TMS320F28x system.
