Abstract
An apparatus and method is provided for correcting data words resulting from a package fail within a memory array in which coded data is divided into a plurality of multi-bit packages of b bits each. The coded data comprises n-bit words with r error correcting code bits and n-r data bits. The invention is capable of correcting one package which has suffered at least one hard failure. The invention correcting exploits single error correcting (SEC)-and double error detecting (DED) codes, requiring no additional check bits, which give a syndrome when the data word has suffered an error coming from at least one error in a package.
