Abstract: An antifuse cell includes an antifuse capacitor that is activatable with a breakdown voltage to provide an electrically conductive path through the capacitor. A pull-up transistor is coupled to the antifuse capacitor. A current path of the pull-up transistor is arranged in parallel with the antifuse capacitor. A shooting transistor is coupled to the pull-up transistor with the current paths of the pull-up transistor and a current path of the shooting transistor cascaded to each other.
