ABSTRACT:
An error correction code for encoding the presence of a special uncorrectable error as well as its type. In the encoder, modification logic modifies the regular data symbols to indicate the type of special uncorrectable error. The encoder appends to the regular data symbols a special uncorrectable error symbol indicating the presence of a special uncorrectable error to form an extended data word, which is encoded to generate a code word. In the decoder, a syndrome generator generates a syndrome vector using an assumed value for the special uncorrectable error symbol indicating the absence of a special uncorrectable error, while a syndrome decoder determines the presence of the special uncorrectable error by determining the presence of an error in the assumed value of the special uncorrectable error symbol. By so using its error detection logic, the decoder makes it unnecessary to actually store or transmit the special uncorrectable error symbol.
