Abstract
Apparatuses, systems, and methods are disclosed for wear leveling for non-volatile memory. An apparatus may include one or more non-volatile memory elements, and a controller. A controller may perform a wear-leveling process for one or more non-volatile memory elements, by periodically updating a logical-to-physical mapping and moving data based on the updated mapping. A controller may detect a wear-based attack for one or more non-volatile memory elements. A controller may change a wear-leveling process in response to detecting a wear-based attack.
