Abstract

In recent years, reliability has become one critical issue in the designs of flash file systems due to the growing unreliability of advanced flash-memory chips. In this paper, a version-based strategy with optimal space utilization is proposed to maintain the consistency among page versions of a file for potential recovery needs with the considerations of the write constraints of multi-level-cell flash memory. A series of experiments was conducted to show that the proposed strategy could improve the reliability of flash file systems with limited management and space overheads.
