Low-density parity-check code based error correction for memory device

A method that facilitates error correcting data, comprising:

• encoding data using a first matrix to yield encoded data and generating parity data associated with the encoded data using a second matrix based on a low-density parity-check code;
• decoding the encoded data based in part on the parity data yielding a decoded symbol sequence;
• multiplying the decoded symbol sequence with a matrix yielding a matrix multiplication result, wherein the matrix comprises a concatenation of the first matrix and the second matrix;
• and
• performing a subsequent iteration of the decoding in response to determining that the decoded symbol sequence violates at least one parity check constraint based on the matrix multiplication result.

A system, comprising:

• means for encoding data using a first matrix to yield encoded data and generating parity data associated with the encoded data using a second matrix based on a low-density parity-check code;
• means for decoding the encoded data based in part on the parity data to yield a decoded symbol sequence;
• means for multiplying the decoded symbol sequence with a matrix to yield a matrix multiplication result, wherein the matrix is a concatenation of the first matrix and the second matrix;
• and
• means for performing a subsequent decoding iteration on the encoded data in response to a determination that the decoded symbol sequence fails to satisfy at least one parity check constraint based on the matrix multiplication result.
