Most mobile devices are equipped with a NAND flash memory even if it has characteristics of not-in-place update and asymmetric I/O latencies among read, write, and erase operations: write/erase operations are much slower than a read operation in a flash memory. For the overall performance of a flash memory system, the buffer replacement policy should consider the above severely asymmetric I/O latencies. However, existing LRU buffer replacement algorithm cannot deal with the above problem. This paper proposes the LRU-WSR buffer replacement algorithm that enhances LRU by reordering writes of not-cold dirty pages from the buffer cache to flash storage. The enhanced LRU-WSR algorithm focuses on reducing the number of write/erase operations as well as preventing serious degradation of buffer hit ratio. The experimental results show that the LRU-WSR outperforms other algorithms including LRU, CF-LRU, and FAB1.
