Abstract

Official abstract text for this publication.

Apparatuses, systems, methods, and computer program products are disclosed for error correcting code (ECC) decoding. A soft information module may be configured to determine whether to obtain an indication of the accuracy of a data value for a variable node of an ECC decoder such as a low density parity check (LDPC) code decoder. A score module may be configured to assign and update a score for the variable node. The score may be based on the accuracy indication and on a count of unsatisfied check nodes of the ECC decoder that are associated with the variable node. A precision for the score may be based on an estimated number of errors for the received code word. A check node update module may be configured to update check nodes associated with the variable node based on the score.

First claim

Opening claim text (preview).

What is claimed is: 1. A method comprising: determining, based on an estimated number of errors for a code word received by an error correcting code (ECC) decoder, whether to obtain an indication of accuracy for data values of the received code word; and correcting one or more errors in the received code word based on the accuracy indication using the ECC decoder, in response to determining to obtain the accuracy indication, by assigning scores to the data values based on the ac…
