Abstract: An IC device includes an integrated capacitor and anti-fuse. Prior to programming of the anti-fuse, electrical current is configured to flow siloed between a first circuit element and a second circuit element through a first VIA. The anti-fuse may be programed by applying a fusing voltage to a second VIA to charge an anti-fuse plate. Within the anti-fuse, the anti-fuse plate is separated from the first capacitor plate by a dielectric. The fusing voltage causes an electric field between the plates to exceed a breakdown field strength of the dielectric which results in an electric arc between the anti-fuse plate and the capacitor plate. The electric arc fuses or otherwise joins the anti-fuse plate and the capacitor plate. Functionality of the IC device may be altered by allowing or driving current from the first circuit element or the second circuit element across the fused plates.
