ECC
    n 1: (telecommunication) a coding system that incorporates extra
         parity bits in order to detect errors [syn: {error
         correction code}, {ECC}]
    

error detection and correction
ECC
EDAC

   <algorithm, storage> (EDAC, or "error checking and
   correction", ECC) A collection of methods to detect errors in
   transmitted or stored data and to correct them.  This is done
   in many ways, all of them involving some form of coding.  The
   simplest form of error detection is a single added {parity
   bit} or a {cyclic redundancy check}.  Multiple parity bits can
   not only detect that an error has occurred, but also which
   bits have been inverted, and should therefore be re-inverted
   to restore the original data.  The more extra bits are added,
   the greater the chance that multiple errors will be detectable
   and correctable.

   Several codes can perform Single Error Correction, Double
   Error Detection (SECDEC).  One of the most commonly used is
   the {Hamming code}.

   At the other technological extreme, cuniform texts from about
   1500 B.C. which recorded the dates when Venus was visible,
   were examined on the basis of contained redundancies (the
   dates of appearance and disappearance were suplemented by the
   length of time of visibility) and "the worst data set ever
   seen" by [Huber, Zurich] was corrected.

   {RAM} which includes EDAC circuits is known as {error
   correcting memory} (ECM).
