Abstract
Miscorrection detection for error correction codes using bit reliabilities is disclosed, including: receiving a plurality of reliabilities corresponding to respective ones of a plurality of read values; receiving one or more proposed corrections corresponding to one or more of the plurality of read values; and determining a miscorrection metric based at least in part on one or more of the plurality of reliabilities corresponding to the one or more of the plurality of read values.
Claims21
A system, comprising:
- an error correction decoder configured to:
- generate one or more proposed corrections corresponding to one or more of a plurality of read values, wherein the plurality of read values corresponds to a codeword;
- and
- a miscorrection detector configured to:
- receive a plurality of reliabilities corresponding to respective ones of the plurality of read values;
- receive the one or more proposed corrections corresponding to the one or more of the plurality of read values;
- and
- determine a miscorrection metric based at least in part on one or more of the plurality of reliabilities corresponding to the one or more of the plurality of read values.
