Design and implementation of NAND Flash files system based on the double linked list

摘要

Aiming at application of NAND Flash memory in embedded system, a double linked list NAND Flash files system was presented, and the storage structure was improved meanwhile. This file system stores the documents record and relevant documents data directly bound in same storage block. The file pointer of this file system adopted double linked list structure, and it can be realized that a flexible two-way data search in forward or backward with file pointer. It is a new type, reasonable and practical, suitable for embedded multimedia applications Flash file system, effectively improved the data retrieval rate, and extended the Flash using life.
