Abstract: A method and a system for data rebuilding and a memory control circuit unit thereof are provided. The method includes reading a plurality of physical-logical mapping information and a plurality of time information corresponding to the physical-logical mapping information stored in a rewritable non-volatile memory module. The method also includes sorting the plurality of physical-logical mapping information according to the plurality of time information corresponding to the physical-logical mapping information. The method further includes rebuilding a logical-physical mapping table according to the sorted plurality of physical-logical mapping information, and storing the rebuilt logical-physical mapping table into a buffer.

Abstract: A memory management method, and a memory control circuit unit and a memory storage apparatus using the same are provided. The method includes associating physical erasing units with a data area or a spare area, configuring a plurality of logical addresses for mapping to the physical erasing units, and obtaining a garbage collection threshold based on a plurality of valid logical addresses among the logical addresses, and the physical erasing units mapping to the valid logical addresses are associated with the data area. The method further includes performing a garbage collection operation on the data area if the number of the physical erasing units associated with the data area is no less than the garbage collection threshold.
