摘要：
The present invention provides a method for managing a flash memory module, wherein the method comprises: reading a logical address to physical address (L2P) mapping table from the flash memory module; compressing the L2P mapping table to generate a compressed mapping table, wherein the compressed mapping table records a reference physical address and whether a corresponding physical address of each logical address is the reference physical address plus an offset value; and when receiving a read command asking for reading data corresponding to a specific logical address, referring to the compressed mapping table to determine a specific physical address corresponding to the specific logical address, and reading the data from the flash memory module according to the specific physical address.
