Abstract:
1. A memory controlling method for a memory storage apparatus, wherein the memory storage apparatus has a rewritable non-volatile memory module, and the rewritable non-volatile memory module has a plurality of memory dies, the memory controlling method comprising: 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; grouping the memory dies into a plurality of memory die groups; applying a first erasing mode to erase data stored in the memory dies when the transmission mode belongs to the first transmission mode, wherein at least a part of the memory die groups are enabled simultaneously in the first erasing 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 any two of the memory die groups are not enabled simultaneously in the second erasing mode.
