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. WebMay 20, 2012 · Atmel says each memory cell is rated for 100,000 write/erase cycles. They also provide an application note, which describes how to perform wear levelling. Here is a summary of the application note. By alternating writes across two memory addresses, we can increase the erase/write to 200,000 cycles. Three memory addresses gives you …
