A flash memory management method for managing a plurality of physical units of a flash memory chip is provided. The flash memory management method includes grouping a portion of the physical units into a data area and a spare area; configuring a plurality of logical units and setting mapping relationships between the logical units and the physical units of the data area. The flash memory management method further includes receiving data and writing the data into the physical unit mapped to a second logical unit among the logical units, and the data belongs to a first logical unit among logical units. Accordingly, the flash memory management method can effectively reduce the number of times for organizing valid data, thereby reducing the time for executing a host write-in command.
