Embodiments include device, storage media, and methods for decoding a codeword of encoded data. In embodiments, a processor may be coupled with a decoder and configured to multiply the codeword and a parity-check matrix of the encoded data to produce a syndrome. If the syndrome is non-zero then the processor may identify a bit error in the codeword based at least in part on a comparison of the syndrome to one or more columns of the parity-check matrix. Other embodiments may be described and claimed.
