Abstract
A fuse bank includes a fuse link being disposed above and insulated from a substrate. A first doped region in the substrate is a guard ring surrounding the fuse link. A second doped region has the same conduction type as the first doped region and is adjacent the first doped region. An insulation separates the second doped region from the first doped region. A high-impedance semiconductor component connects the first doped region to a first supply potential. The second doped region is connected to a second supply potential.
