Claim 10:
11. A non-volatile memory device configured to be coupled to a controller that is separate and distinct from the non-volatile memory device, wherein the non-volatile memory device is configured to:
decode data;
extract metadata from the decoded data; and
transfer the extracted metadata to the controller, wherein the non-volatile memory device is configured to receive results from the controller comparing the extracted metadata to data stored in a flash translation layer (FTL) table, wherein the non-volatile memory device is further configured to transfer valid data to the controller in response to the comparing performed by the controller, wherein the non-volatile memory device is further configured to assign a new logical block address (LBA) to valid data, wherein the non-volatile memory device is further configured to encode a new codeword with new metadata header for the new LBA.
