Reed–Solomon error correction
As of 2009, the most-common error-correction codes use Hamming or Hsiao codes that provide single-bit error correction and double-bit error detection (SEC-DED). Other error-correction codes have been proposed for protecting memory double-bit error correcting and triple-bit error detecting (DEC-TED) codes, single-nibble error correcting and double-nibble error detecting (SNC-DND) codes, Reed–Solomon error correction codes, etc. However, in practice, multi-bit correction is usually implemented by interleaving multiple SEC-DED codes.
