Abstract

JFFS2 (Journaling Flash File System, version 2) is a popular file system of Linux platform that is employed to manage NAND type flash memory, briefly denoted by NandFlash. Based on JFFS2 mechanism, we propose an effective management method of NandFlash, new flash file system for NandFlash called NFFSNand. Our method focuses on reducing the cycle-leveling degree in a balanced manner. Moreover, NFFSNand can enhance the system performance and prolongs life-cycle of NandFlash. In this study, we verify the system cost, the reliability, and space utilization of NFFSNand are better than JFFS2 by 50% at Samsung SMDK2410X platform
