A flash memory storage system including a flash memory chip, a connector, and a flash memory controller is provided. The flash memory controller configures a plurality of logical addresses and maps the logical addresses to a part of the physical addresses in the flash memory chip, and a host system uses a file system to access the logical addresses. Besides, the flash memory controller identifies a deleted logical address among the logical addresses and marks data in the physical address mapped to the deleted logical address as invalid data. Thereby, the flash memory storage system can identify data deleted by the host system in the physical addresses, so that the time for sorting data can be effectively reduced.
