A fuse state detection circuit is comprised of a first fuse element, a second fuse element, and an output for carrying an output signal, the output signal represents a first logic state when the first fuse element is blown and the second fuse element is unblown and the output signal represents a second logic state when the first element is unblown and the second element is blown. The fuse state detection circuit produces an output signal whose state is recoverable from a negative triggering event and is capable of resolving itself to the correct state without the need for a reset pulse. Methods of using the fuse state detection circuit, such as a method of using fuse elements to control a setting within an electronic circuit, the improvement comprising using a pair of fuse elements to control a single setting, are also given.
