This draft 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. Purpose This draft standard provides a method to utilize error correction coding in non-volatile memories. For this purpose@ a two-level code construction method based on LDPC codes along with the decoding method is presented. This scheme outperforms the traditional method@ while having slightly higher memory requirements and negligible delay.
