Summary :

The class of codes described in this paper is used for Single b-Adjacent bit-group Error Correction (SbEC). This is especially useful in large memory systems which use integrated semiconductor memory chips, each containing b-output bits. The proposed codes have odd-weight-column H-matrix characteristic and superior error detection capability, and facilitates the construction of modularized parallel high speed encoding / decoding network through rotational coding techniques. For a special case of b1, this class of codes is equivalent to the optimal odd-weight-column SEC-DED (Single Error Correcting - Double Error Detecting) codes. A computation indicates that the odd-weight-column SbEC codes have better error detection capability than the conventional SbEC codes.
