    Abstract: A memory management method is provided according to an exemplary embodiment of the disclosure. The method includes: obtaining a valid data parameter based on a valid data amount of valid data stored in a plurality of physical erasing units, and obtaining a first threshold value based on the valid data parameter. The method also includes: obtaining a first determination parameter based on a number of a plurality of first physical erasing units, and the first physical erasing units are physical erasing units being programmed for storing data by using a single-page programming mode. The method further includes: performing a garbage collection operation if the first determination parameter is greater than the first threshold value.
