A programmable fuse circuit is provided with a disabling static current path. The fuse logic circuit includes a controllable switch, load device, and at least one fuse, all of which are connected in a series so as to share a static current path. The controllable switch is preferably a transistor and can be selectively controlled to enable or disable the current path of the programmable fuse circuit. Therefore, by providing the ability to disable the static current path of programmable fuse circuit without having to blow the fuse makes the programmable fuse circuit static current testable. Other applications for the programmable fuse circuit include, for instance, providing a serial number to integrated circuits. |
