Patent ID: 7301810

Claim:
A non-volatile memory system, comprising: a set of non-volatile storage elements; and one or more managing circuits in communication with said set of non-volatile storage elements, said one or more managing circuits perform a read process for a set of non-volatile storage elements using a set of reference values to determine said set of read data stored in said set of non-volatile storage elements, said one or more managing circuits capable of determining that said read data has one or more errors that cannot be corrected by an error correction process and performing a data recovery process if said error correction process is not able to correct said one or more errors, said data recovery process comprises reading non-volatile storage elements adjacent to said a set of non-volatile storage elements and adjusting at least a subset of said reference values based on reading of said non-volatile storage elements adjacent to said set of non-volatile storage elements and performing another one or more read processes for said set of non-volatile storage elements using said adjusted reference values.
