File systems for flash memory that is widely used as a storage device for mobile devices should provide not only high-performance data reads and writes but also a guarantee on the data integrity even on a power failure. In this paper, we explain the design and implementation of a file system for flash memory that considers flash memory's physical characteristics and the data layout in the file system to give an optimized write performance. This file system guarantees the reliability against various system failures including a power failure by using the transaction concept in write processing. In addition, the file system minimizes the memory usage by using a simple static mapping. In the paper, we also describe the implementation of the file system and compare its performance with other existing flash memory file systems. |
