Memory error identification based on corrupted symbol patterns

A method, comprising:

• receiving a codeword across a first channel coupling a memory controller to a buffer, and a second channel coupling the buffer to a memory, wherein a first channel width differs from a second channel width, and the codeword includes a plurality of data symbols and at least one check symbol, wherein each of the plurality of symbols is formed from a plurality of bursts based on data access of the memory;
• correcting, using a memory controller and the at least one check symbol, a memory error based on a corrupted symbol pattern of the codeword;
• and
• discriminating between a chip failure, a first pin failure of the first channel, and a second pin failure of the second channel, as being a type of the memory error, according to the corrupted symbol pattern.

A non-transitory computer readable medium having instructions stored thereon executable by a processor to cause a memory controller to:

• receive a codeword across a first channel, coupling a memory controller to a buffer, and a second channel coupling the buffer to a memory, wherein a first channel width differs from a second channel width, and the codeword includes a plurality of data symbols and at least one check symbol, wherein each of the plurality of symbols is formed from a plurality of bursts based on data access of the memory;
• correct, using the memory controller and the at least one check symbol, a memory error based on a corrupted symbol pattern of the codeword;
• and
• discriminate between a chip failure, a first pin failure of the first channel, and a second pin failure of the second channel, as being a type of the memory error, according to the corrupted symbol pattern.
