Abstract: This paper introduces a flash based file system for smart card. At the least cost, it achieves storage reclaim and reuse on the card, provides a damaged flash block management mechanism, averages the flash block's erase operation to prolong the flash storage life-span, and offers recovery approach for data lost by accident. The simulation confirms the file system's validity.
