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.

Abstract: A memory controlling method, a memory controller and a memory storage apparatus are provided. The method includes identifying whether a transmission mode between the memory storage apparatus and a host system belongs to a first transmission mode or a second transmission mode and grouping memory dies of the memory storage apparatus into a plurality of memory die groups. The method also includes applying a first erasing mode to erase data stored in the memory dies when the transmission mode belongs to the first transmission mode and applying a second erasing mode to erase the data stored in the memory dies when the transmission mode belongs to the second transmission mode, wherein at least a part of the memory die groups are enabled simultaneously in the first erasing mode and any two of the memory die groups are not enabled simultaneously in the second erasing mode.
