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 20):
The memory storage apparatus as claimed in  claim 19 , wherein the operation of the memory control circuit unit further configured for 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 the data stored in the first physical erasing unit to the second physical erasing unit comprises:\n the memory control circuit unit is further configured for updating a logical address-physical address mapping table for associating the second physical erasing unit with the first area, and the memory control circuit unit is further configured for updating a spare area physical erasing unit queue table for associating the first physical erasing unit with the second area.
