IEEE 1890-2018

This standard specifies a method to construct two-level low-density parity-check (LDPC) codes and to utilize them as the error correction coding (ECC) scheme in non-volatile memories (NVM). The encoding and decoding methods as well as the implications on memory and overall system latency are presented. The simulation results comparing the two-level code construction scheme and the traditional one-level scheme, as well as the parity check matrices for several LDPC code rates and lengths are provided.
