Wear-leveling techniques in NAND flash devices

Wear leveling is a process that helps reduce premature wear in NAND flash devices. The most common implementation of wear leveling occurs in the NAND flash controller, which manages access to the memory device and determines how the NAND flash blocks are used.

This application note highlights the importance of wear leveling, explains two primary wear-leveling techniques—static and dynamic—and calls attention to other considerations involved in implementing wear leveling.
