ALEXANDRIA, Va., Aug. 26 -- United States Patent no. 12,401,377, issued on Aug. 26, was assigned to SK hynix Inc. (Gyeonggi-do, South Korea).
"Error correction based on asymmetric ratio" was invented by Meysam Asadi (Livermore, Calif.) and Fan Zhang (Fremont, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques for decoding a low-density parity check (LDPC) can include determining an asymmetric ratio of bit errors read as logic zero to bit errors read as logic one. The energy of each variable node of the LDPC codeword can be computed. For each variable node having an energy greater than a threshold energy, the variable node can be added to a collection of candidate bits for bit flipping. The asym...
