Abstract
A circuit for programming a fuse is disclosed. The circuit includes a voltage supply terminal (Vp) and a latch circuit comprising a p-channel transistor and an n-channel transistor (208-214). A semiconductor controlled rectifier (206) in the circuit includes at least one terminal of the p-channel transistor. A fuse (200) is coupled between the voltage supply terminal and the semiconductor controlled rectifier. The fuse is programmed in response to the semiconductor controlled rectifier.
