Abstract
This paper introduces an improved algorithm to distribute erase operations evenly across the large-capacity flash memory system. Such implementation requires the wear-leveling mechanism to deal with a large proportion of data that is not frequently updated. The original algorithm shows a good performance in lowering memory consumption but can not well satisfy that requirement. Detailed analysis show how the problem occurs, and our work focuses on addressing this problem. Moreover, a FIFO structure is used in this algorithm to improve the efficiency of basic hot-cold data swapping. The simulation results demonstrate that the proposed algorithm provides a much higher performance than the previous scheme, while consuming roughly the same memory space.
