Abstract: A method and system for intelligent bit recovery identifies toggling bits, which change in value from one read to the next, and examines a subset of potential bit patterns. The subset is a fraction of the potential bit patterns, and is based on an understanding of the flash memory and the problems that may cause the toggling bits. The intelligent bit recovery may analyze at least one aspect of the flash memory to identify a problem, or plurality of problems, that is potentially causing the toggling bits, and to select the subset of potential bit patterns as potential solutions. The subset of potential bit patterns examined by the intelligent bit recovery is a small fraction of the entire set of potential bit patterns.

Abstract: A method and system intelligent bit recovery is provided. The intelligent bit recovery determines which bits are toggling, and examines a subset of the potential bit patterns to determine which in the subset of potential bit patterns is valid. The subset is a fraction of the potential bit patterns, and is based on an understanding of the flash memory and the problems that may cause the toggling bits. The intelligent bit recovery may analyze at least one aspect of the flash memory to identify which problem is potentially causing the toggling bits, and to select the subset of potential bit patterns as solutions for the determined problem. Or, the intelligent bit recovery selects potential bit patterns for multiple potential problems. In either way, the subset of potential bit patterns examined by the intelligent bit recovery is a small fraction of the entire set of potential bit patterns.
