Description: Construction techniques for systematic SEC-DED codes with single byte error detection and partial correction capability for computer memory systems This correspondence proposes three new techniques to construct a class of codes that extends the protection provided by previous single error correcting (SEC)-double error detecting (DED)-single byte error detecting (SBD) codes. The proposed codes are systematic odd-weight-column SEC-DED-SBD codes providing also the correction of any odd number of erroneous bits per byte, where a byte represents a cluster of \(b\) bits of the codword that are fed by the same memory chip or card. These codes are useful for practical applications to enhance the reliability and the data integrity of byte-organized computer memory systems against transient, intermittent, and permanent failures. In particular, they represent a good tradeoff between the overhead in terms of additional check bits and the reliability improvement, due to the capability to correct at least \(50%\) of the multiple errors per byte.
