Abstract:
Embodiments are generally directed to errors and erasures decoding from multiple memory devices. An apparatus may include logic to store a portion of an error correction codeword in each of multiple memory devices, and logic to decode errors and erasures for the memory devices. The decoding of the errors and erasures includes reading the portions of the error correction codeword from a subset of the memory devices to generate a partial codeword, with the subset excluding at least one of the memory devices. The decoding of the errors and erasures further includes decoding errors and erasures of the plurality of memory devices based at least in part on the partial codeword if the errors and erasures can be decoded from the partial codeword, and, upon determining that the errors and erasures cannot be decoded from the partial codeword, then reading the one or more portions of the error correction codeword from the memory devices excluded from the first subset to generate a complete codeword.
