Abstract
Fuses that selectively disable functional blocks of a circuit are arranged in a multistage structure, wherein if any fuse element in the multistage structure permanently switches off a part of the circuit, no other fuse element in the multistage structure can affect the switching off of the part. Master fuses are provided to selectively disable corresponding stages of the multistage structure. Preferably, the master fuses are arranged in a hierarchy, so that a master fuse at a higher level of the hierarchy selectively disables all of the stages at lower levels of the hierarchy.
