A data management method for a rewritable non-volatile memory module including a first memory unit and a second memory unit is provided. The method includes: grouping erasing units of the first memory unit into a data area and a spare area; and grouping the physical erasing units of the second memory unit into a data backup area and a command recording area; configuring multiple logical addresses to map to the physical erasing units associated with the data area; receiving a write command which instructs writing data; writing the data to a physical erasing unit associated with the spare area, and writing the data to a physical erasing unit associated with the data backup area; recording at least a portion of the write command in a physical erasing unit associated with the command recording area. Accordingly, data is backuped in the rewritable non-volatile memory module.

Data management method, memory controller and memory storage device

A method for managing commands in a command queue, a memory controller, and a memory storage apparatus are provided. The method includes: storing at least one first command in a command queue register according to a plurality of first indication bits and updating the first indication bits according to a current storage status of the command queue register; generating a plurality of updated second indication bits according to the updated first indication bits and a plurality of second indication bits. The method also includes: obtaining at least one first command index corresponding to at least one register block storing the at least one first command in the command queue register according to the updated second indication bits and adding the at least one first command index into a command index register; executing commands corresponding to un-executed command indices in the command queue register.
