Abstract
A storage device syndrome-weight-based error correction system includes a syndrome-weight-based error correction subsystem coupled to a storage subsystem in a chassis. The syndrome-weight-based error correction subsystem performs a plurality of respective first error correction hard decoding operations on the storage subsystem that each utilize respective read voltage thresholds and that each generate a respective final codeword candidate having a respective syndrome weight. The syndrome-weight-based error correction subsystem identifies a first syndrome weight of a first final codeword candidate that was generated via the performance of one of the plurality of respective first error correction hard decoding operations that utilized first read voltage thresholds and that is lower than the syndrome weights of the final codeword candidates generated via the performance of the others of the plurality of respective first error correction hard decoding operations, and performs error correction soft decoding operations using the first read voltage thresholds.
