Page Replacement Algorithms for NAND Flash Memory Storages

Free registration required

Executive Summary

Recently, embedded systems usually employ NAND flash memory as data storages because of its small size, lightweight, shock resistance, and low-power consumption. The I/O operations of NAND flash memory are significantly different from those of traditional hard disk. For example, a read or a write operation in NAND flash memory is performed by the unit of flash page, and an erase operation should be preceded for a group of adjacent flash pages called block before a write operation is performed.
