Combined secure mac and device correction using encrypted parity with multi-key domains

A computer-implemented method, comprising:

• generating an error correction code for a memory line, the memory line comprising a first plurality of data blocks, wherein the error correction code comprises a first plurality of parity bits and a second plurality of parity bits;
• applying a domain-specific function to the second plurality of parity bits to generate a modified block of parity bits;
• generating a metadata block corresponding to the memory line, wherein the metadata block comprises the error correction code for the memory line and at least a portion of the modified block of parity bits;
• encoding the first plurality of data blocks to generate a first encoded data set;
• encoding the metadata block to generate a first encoded metadata block;
• and
• store the first encoded data set and the first encoded metadata block on a memory module.

A non-transitory computer-readable medium comprising instructions which, when executed by a processor, configure the processor to:

• generate an error correction code for a memory line, the memory line comprising a first plurality of data blocks, wherein the error correction code comprises a first plurality of parity bits and a second plurality of parity bits;
• apply a domain-specific function to the second plurality of parity bits to generate a modified block of parity bits;
• generate a metadata block corresponding to the memory line, wherein the metadata block comprises the error correction code for the memory line and at least a portion of the modified block of parity bits;
• encode the first plurality of data blocks to generate a first encoded data set;
• encode the metadata block to generate a first encoded metadata block;
• and
• store the first encoded data set and the first encoded metadata block on a memory module.
