Abstract
A valid data merging method, a memory control circuit unit, and a memory storage device are provided. The method includes: obtaining a first system parameter corresponding to a first region and a second system parameter corresponding to a second region; determining whether the first system parameter is greater than the second system parameter; selecting a third physical erasing unit from the second region preferentially and performing a valid data merging operation by using the third physical erasing unit when the first system parameter is greater than the second system parameter; and selecting a fourth physical erasing unit from the first region preferentially and performing the valid data merging operation by using the fourth physical erasing unit when the first system parameter is not greater than the second system parameter.
