Abstract
The lifespan of flash memory has a close connection with its wear-leveling level. However, YAFFS2, a popular embedded file system does a poor work on it. This paper introduces a novel approach, easy to be achieved, to improve its wear-leveling level and retain its original format and strengthens. The new cold-data method is tested using real YAFFS2 file system for different parameters. Our results demonstrate that it is capable of improving the wear-leveling level as well as prolong devices lifespan significantly.
