WebAug 6, 2024 · There are three types of Wear Leveling: Dynamic, Static and Global. Dynamic wear leveling only handles free space and ensures that write behavior will only occur in blocks that have a lower erase count in the same space. Static wear leveling considers the entire Flash die, including blank areas and blocks to which have been written. Webincoming data being written to a flash block can be selected for wear leveling and flash blocks that contain data cannot be selected. Figure 2 shows differences between the wear leveling methods where dynamic wear leveling is easier to implement and static wear leveling is better for extending the life of NAND flash memory.
