摘要： A data writing method for writing updated data from a host into a memory module is provided. Herein, some physical units of the memory module are gotten to be global random physical units for storing data from the host. The method includes determining whether the updated data is sequential data and determining whether a logical page corresponding to the updated data is a start logical page. The method further includes getting a blank physical unit from the physical units as a new global random physical unit and writing the updated data into the new global random physical unit when the updated data is the sequential data and the logical page corresponding to the updated data is the start logical page. Accordingly, the method can write updated data belonging to the same logical unit into the same physical unit, thereby shortening the time for executing write commands.

摘要： A memory management method for managing physical units of a rewritable non-volatile memory module is provided. In the method, the physical units are grouped into at least a data area and a free area. The method includes obtaining empty physical units from the free area to configure a first global random area and obtaining empty physical units from the data area to configure a second global random area. The method further includes using the physical units of the first global random area to write updated data, and using the physical units of the second global random area to write other updated data after the physical units of the first global random area are written full of the updated data. Accordingly, the method can increase the storage space of a global random area, and thereby reduces data merging operations and shortens the time for executing a write command.
