Abstract

A storage device syndrome-weight-based error correction system includes a syndrome-weight-based error correction subsystem that is coupled to a storage subsystem in a chassis. The syndrome-weight-based error correction subsystem performs a first error correction hard decoding operation on the storage subsystem that utilizes first read voltage thresholds and that generates a first final codeword candidate having a first syndrome weight. The syndrome-weight-based error correction subsystem then performs error correction hard decoding read voltage threshold real-time search operations to determine second read voltage thresholds, and performs a second error correction hard decoding operation on the storage subsystem that utilizes the second read voltage thresholds and that generates a second final codeword candidate having a second syndrome weight. If the syndrome-weight-based error correction subsystem determines that the first syndrome weight is less than the second syndrome weight, it performs error correction soft decoding operations using the first read voltage thresholds.
