Abstract: A valid data merging method, a memory controller and a memory storage apparatus are provided. The method includes: grouping physical erasing units in a data area to at least a first group and a second group; selecting a first physical erasing unit from the second group; and copying valid data of the first physical erasing unit to a second physical erasing unit. A trim table recording special type data of the physical erasing units of the first group is not stored in a non-volatile rewriteable memory module, and a trim table recording special type data of the physical erasing units of the second group is stored in the non-volatile rewriteable memory module. The valid data does not include the special type data of the first physical erasing unit.

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.

Abstract translation: 提供存储器管理方法，存储器控制电路单元和存储器存储装置。 该方法包括：接收第一写入命令并将与第一写入命令相对应的数据写入第一备用物理擦除单元; 检测除第一备用物理擦除单元之外的第二备用物理擦除单元的量; 确定所述第二备用物理擦除单元的量是否小于阈值; 以及如果所述第二备用物理擦除单元的量小于所述阈值，则执行第一过程。 第一个过程包括：将物理擦除单元中的有效数据移动到至少一个第三备用物理擦除单元; 以及将阈值从第一阈值调整到第二阈值。
