ABSTRACT:
To improve both the yield and the reliability of manufactured integrated circuits incorporating redundancy circuits, unused redundancy circuits are additionally used to bracket a defective circuit or circuits identified through production testing by replacing adjacent circuits which have tested satisfactorily and which would otherwise not be replaced, but which are considered to be prone to subsequent failure.
