Abstract

A memory management method, a memory control circuit unit and a memory storage apparatus are provided. The method includes: receiving a first write command and writing data corresponding to the first write command into a first spare physical erasing unit; detecting an amount of second spare physical erasing units excluding the first spare physical erasing unit; determining whether the amount of the second spare physical erasing units is less than a threshold value; and performing a first procedure if the amount of the second spare physical erasing units is less than the threshold value. The first procedure includes: moving valid data in the physical erasing units into at least one third spare physical erasing unit; and adjusting the threshold value from a first threshold value to a second threshold value.
