ABSTRACT:
A system including an semiconductor chip with a hard-coded bit changeable in any single metal layer of the semiconductor chip has been presented. In one embodiment, the system includes a graphics chip and an input/output controller hub. The input/output controller hub includes an integrated circuit having a set of metal layers, a logic circuit, and a set of cells. The logic circuit has a plurality of input terminals and an output terminal to output the hard-coded bit, wherein a value of the hard-coded bit is changeable during fabrication in any single one of the metal layers. Further, each of the set of cells is on a distinct one of the metal layers, each cell having an output pin directly coupled to one of the input terminals of the logic circuit. Each cell further includes a connector to electrically couple the output pin to one of a first via stack and a second via stack, wherein the first via stack and the second via stack are electrically coupled to a first supply voltage and a second supply voltage, respectively.
