Research and design of 3G file system for smart card
Mei Xiao-hu · Journal of Computer Applications · 2010
Research and design of three generation file system for smart card on flash memory were made,introducing log technology and power failure protection to assure smart card's file system reliability,data consistency and integrality.Memory space was assigned according to byte.Mechanisms of valid space collection and reuse improve the using rate of memory space.Technology of wear leveling and page mapped prolong the flash storage life-span,and the design of efficiency memory management improves the rate of data retrieval.Consequently,the whole performance of smart card is strengthened.The simulation makes sure the file system fit 3G EVDO card.
