Abstract
An integrated circuit decoupling capacitor is divided into a plurality of discrete segments. The segments are connected electrically in parallel and are redundant to an extent that if one segment (or if desired more than one segment) fails, the remaining segments have sufficient capacitance to provide the required decoupling function. Each decoupling capacitor segment has a fuse connected in series with it. The fuse opens in response to a fault in a decoupling capacitor segment that would otherwise cause that segment to short the power supply to ground.
