Abstract: Provided is a memory system comprising a plurality of memory components. The ECC decoding is configured to construct first and second codewords from a single set of data within the plurality of memory components and perform error correction code (ECC) decoding on the first and second codewords received read from the plurality of memory components wherein the ECC decoding is configured to (i) detect random errors in the first received codeword and (ii) use data associated with the detected random errors to correct erasures in the second received codeword.

CPC classification number: G06F11/1068 ,  G06F11/1004

Abstract: Provided is an apparatus comprising a search engine configured to (i) receive parallel input of a set of syndrome polynomial products corresponding to a set of ECC words and (ii) produce corresponding sets of polynomial roots therefrom and a sequence detector configured to identify sequences within each of the polynomial roots within the set of roots. Also provided is sequence check logic for (i) combining the identified sequences within each of the polynomial roots and (ii) performing a sequence check of the combined identified sequences to determine whether only one of the identified sequences if valid; and an error location generator to derive an error location in each of the ECC words within the set responsive to the valid sequence.
