Summary:The invention provides a memory management method, a memory storage device and a memory control circuit unit. The method is used for a rewritable nonvolatile memory module, and the rewritable nonvolatile memory module comprises a plurality of first-class entity units and a plurality of second-class entity units. The method comprises the following steps of: grouping part of entity units in a second type of entity units into a first reserved area and a second reserved area, wherein the entity units belonging to the first reserved area and the second reserved area are reserved in data arrangement operation for use; and performing a first data sorting operation including: collecting the first data from the source unit; selecting a target unit from the first reserved area or the second reserved area according to the attribute of the source unit; and storing the first data in the target unit. Therefore, the writing stability of the rewritable nonvolatile memory module during the period of executing the data arrange
