Synergetic deduplication

摘要

Flash memory devices can be implemented with deduplication mechanism through a synergetic deduplication mapping that combines the logical-to-physical address mapping of the flash memory devices with the deduplication mapping. A deduplication algorithm can be implemented in the application layer, which can freely communicate with the flash memory devices and perform computationally expensive operations.

1. An address mapping table adapted for use with a solid state drive, the address mapping table comprising:
logical addresses of data, wherein the data is configured to be stored in memories of the solid state drive; physical addresses of the memories, wherein the address mapping table is configured to map the logical addresses to the physical addresses, wherein the address mapping table is further configured to map logical addresses of duplicated portions of the data to same physical addresses of memories of the solid state drive.
