Abstract
A wear leveling limit and/or an overall erase count threshold used for activating wear leveling in a non-volatile memory may be adjusted by determining a stage according to a highest erase count, and determining the wear leveling limit and/or the overall erase count threshold corresponding to the stage. Wear leveling may then be performed according to the wear leveling limit and/or the overall erase count threshold.
