Storage device syndrome-weight-based error correction system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a syndrome-weight-based error correction engine that is configured to:
• perform, on a storage subsystem that is coupled to the processing system, a plurality of respective first error correction hard decoding operations that each utilize respective read voltage thresholds and that each generate a respective final codeword candidate having a respective syndrome weight;
• identify 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
• perform, on the storage subsystem, error correction soft decoding operations using the first read voltage thresholds.

A method for correcting errors in a storage device based on syndrome weights, comprising:

• performing, by a syndrome-weight-based error correction subsystem on a storage subsystem, a plurality of respective first error correction hard decoding operations that each utilize respective read voltage thresholds and that each generate a respective final codeword candidate having a respective syndrome weight;
• identifying, by the syndrome-weight-based error correction subsystem, 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
• performing, by the syndrome-weight-based error correction subsystem on the storage subsystem, error correction soft decoding operations using the first read voltage thresholds.
