| Abstract: | The physical component of Flash memory is introduced briefly and the necessity of wear-leveling for FAT flash file system is discussed mainly in this paper.According to the physical component characteristic of flash memory,the wear-leveling algorithm was designed in the process of garbage-collection.This algorithm includes dynamic wear-leveling algorithm amd static wear-leveling algorithm depending on the different erasing times of block. |
