AbstractFlash memory has been widely considered as a good alternative for storage system implementations because it offers superior vibration tolerance and power efficiency, compared to hard-disks. Because of its unique characteristics, direct applications of disk management methods over flash memory might result in performance degradation and even the reducing of the lifetime. The management issues become even more challenging, especially when the capacity of flash memory increases significantly in the past few years. In this paper, we summarize our work on several important issues in flash memory management, where system performance and management overheads are considered. The capability of the proposed methodology was evaluated by a series of experiments to provide more insights in system designs.
