Abstract : Document describes circuitry and a method for correcting errors in binary data which is stored in memory and subject to errors upon recall therefrom. The technique involves generating a redundant byte related to each original byte to be stored, storing both bytes in memory, and applying the recalled bytes to a decoder designed to correct the errors. If more than a single adjacent error per byte is expected, it is necessary to transpose the bits of the original and redundant bytes before storage so that the bits thereof alternate, and re-transpose the recalled bytes to their original sequence before application to the said decoder.
