Memory packages with buffer die with parallel error detection and correction

A method comprising:

• receiving write data at a buffer die;
• performing, with an error correction code (ECC) circuit of the buffer die, at least a portion of computations to generate a codeword based, at least in part, on the write data, using Reed Solomon (RS) coding;
• providing portions of the codeword from the buffer die to a plurality of memory devices;
• and
• storing the codeword in the plurality of memory devices.

A method comprising:

• retrieving a codeword from at least one of a plurality of memory devices, wherein the codeword was generated from data using Reed Solomon (RS) coding;
• performing, with a corresponding plurality of error correction code (ECC) circuits of the plurality of memory devices, at least a portion of computations to generate a syndrome based, at least in part, on the codeword;
• and
• correcting, with an ECC circuit of a buffer die, an error in the codeword based, at least in part, on the syndrome.
