Abstract
A programmable integrated circuit (see FIG. 10) includes a routing conductor, i.e., 'express wire,' that extends substantially across the array of the integrated circuit. Because of the metal resistance through the long express wire, the express wire is simultaneously supplied with programming current from two different programming voltage terminals. Thus, programming current may be supplied to an electrode of an antifuse being programmed using programming current flowing through two separate programming voltage terminals. One programming voltage terminal supplies programming current via a first programming transistor and a first programming conductor to the express wire near one end of the programming conductor whereas another programming voltage terminal supplies programming current via a second programming transistor and a second programming conductor to the express wire near an opposite end of the express wire. The programming drivers that drive the first and second programming conductors are disposed adjacent opposite sides of the integrated circuit.
