  • Patent number: 12176921
    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.

  • Patent number: 12132499
    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.
