Evaluation of Write Sequence Reordering Based Buffer Replacement Algorithms for Flash Memory Based Systems
Abstract: Many page replacement algorithms have been developed for disk-based systems. All of them consider the hit rate as a key performance measure. Flash memory has different characteristics than hard disks, such as asymmetric I/O latency among read, write, and erase operations. The read operation is faster than the write and erase operation, and it does not support in-place updates. Besides, write operations shorten the life of flash memories. Therefore, the …
