An apparatus for programming a fuse includes a programmable branch comprising a fusable element and a reverse-biased diode connected in series. The programmable branch is connected in parallel with a current boost capacitor. An electrical source or input supplies a current that is sufficient to charge the current boost capacitor to a breakdown voltage of the reverse-biased diode and subsequently melt the reverse-biased diode. Melting the reverse-biased diode may induce a reduction in voltage across the current boost capacitor and result in a current surge through the programmable branch that is sufficient to program (i.e. blow) the fusable element. A corresponding method for programming a fuse is also disclosed.
