Abstract
Circuits for programming an electrical fuse, methods for programming an electrical fuse, and methods for designing a silicon-controlled rectifier for use in programming an electrical fuse. A programming current for the electrical fuse is directed through the electrical fuse and the silicon-controlled rectifier. Upon reaching a programmed resistance value for the electrical fuse, the silicon-controlled rectifier switches from a low-impedance state to a high-impedance state that interrupts the programming current.
