WebDynamic wear leveling The first type of wear leveling is called dynamic wear leveling and it uses a map to link logical block addresses (LBAs) from the OS to the physical flash memory. Each time the OS writes replacement data, the map is updated so the original physical block is marked as invalid data, and a new block is linked to that map entry. WebWear Leveling can be mainly divided into three types: Dynamic, Static, and Global. The greatest difference amongst the three lies in how they average wear.
