摘要：
File system for flash memory usually assumes a form of log-structured file system and it employs garbage collector accordingly. Since a garbage collector may greatly affect the performance of file system, it should be designed carefully considering characteristics of flash memory. In this paper, we suggest a new garbage collector for existing JFFS2 file system. By extensive performance evaluation, we show that the proposed garbage collector achieves improved performance in terms of flash memory consumption rate, increased flash memory life time, and improved wear-leveling.
