Simplified efficient error correction code schemes using multiple codewords

Enacted on a computing system, a method for implementing an asymmetric error correction code scheme with multiple codewords, the method comprising:

• encoding data comprising user data and metadata in a memory module comprising a plurality of dies by:
• logically partitioning the memory module into a plurality of partitions, wherein each partition comprises a plurality of memory segments that includes a memory segment from each of the plurality of dies;
• on a first partition of the plurality of partitions:
• storing a first portion of the user data on one or more memory segments of the first partition;
• and
• storing a first cyclic redundancy check (CRC) codeword and the metadata on a memory segment of the first partition different from the one or more memory segments of the first partition, wherein the first CRC codeword is generated based on the first portion of the user data and the metadata;
• and
• storing parity data on one of the plurality of dies.
