Abstract:
A fuse circuit that permits a fuse to be selected and programmed using a single fuse pad. The fuse circuit includes a fuse pad to receive a first voltage, a fuse coupled in series with a voltage controlled switch between the fuse pad and a reference node, and a switch control circuit coupled in series between the fuse pad and the reference node and in parallel with the fuse and the voltage controlled switch, the switch control circuit being configured to select and program the fuse responsive to the first voltage received at the fuse pad. The fuse pad may subsequently be grounded and a sense circuit may be coupled to the fuse to measure a voltage dropped across the fuse to determine whether the fuse has been programmed.
