Abstract:
A wear leveling method for a rewritable non-volatile memory module, a memory control circuit unit, and a memory storage apparatus are provided. The rewritable non-volatile memory module includes a plurality of physical erasing units. The method includes: recording an operation value of each of the physical erasing units; recording a usage situation value of each of the physical erasing units; and selecting a first physical erasing unit and a second physical erasing unit from the physical erasing units according to the operation values of the physical erasing units and the usage situation values of the physical erasing units and copying valid data stored in the first physical erasing unit to the second physical erasing unit.

Claim (Index 5):
The wear leveling method as claimed in  claim 1 , wherein the step of selecting the first physical erasing unit and the second physical erasing unit from the physical erasing units according the operation values of the physical erasing units and the usage situation values of the physical erasing units and copying data stored in the first physical erasing unit to the second physical erasing unit comprises:\n determining whether a greatest usage situation value in the usage situation values of the physical erasing units of the first area is equal to or greater than a first threshold; selecting the second physical erasing unit in the physical erasing units of the second area and selecting the first physical erasing unit in the physical erasing units of the first area if the greatest usage situation value is equal to or greater than the first threshold; determining whether a difference value between the operation value of the second physical erasing unit and the operation value of the first physical erasing unit is equal to or greater than a second threshold; and copying the data stored in the first physical erasing unit to the second physical erasing unit if the difference value is equal to or greater than the second threshold.
