A fuse circuit includes a fuse configured for programming a configuration of an integrated circuit device and a resistive element having a known resistance value operably coupled in parallel with the fuse. The fuse and the resistive element form a parallel circuit configured for quickly sensing a state of the fuse in relation to the known value of the resistive element. In one embodiment, the device may further include a sense circuit operably coupled to the parallel circuit combination of the fuse and the resistive element. The sense circuit is configured to sense one of a FUSED state and an UNFUSED state of the fuse, for example, based on a comparison between a reference resistance and a FUSED resistance of the fuse when coupled to the known resistance. The fuse may comprise a programmable fuse, and the resistive element may comprise a MOS transistor.
