Patent ID: 7687921

Claim:
An electronic device comprising: a substrate including a plurality of bonding pads; a first integrated circuit (IC) die mounted on the substrate, the first IC die including a first electronic circuit, first functional contact pads that are internally connected to said electronic circuit, and a first electrically isolated step pad; a plurality of first bonding wires extending between said substrate and said first IC die, said first bonding wires including a first step wire connected between a first bonding pad of said plurality of bonding pads and said first electrically isolated step pad; a second IC die mounted on the first IC die in an offset stacked arrangement, the second IC die including a second electronic circuit and second functional contact pads that are internally connected to said second electronic circuit, the second IC die also including zero or more second electrically isolated step pads; and a plurality of second bonding wires including one or more second die-to-die wires extending between said first IC die and said second IC die, and zero or more second intra-die wires, wherein each of said zero or more second intra-die wires is connected between an associated first one of said second electrically isolated step pads and one of an associated one of said second functional contact pads, and an associated second one of said second electrically isolated step pads, and wherein said first step wire and at least one wire of said plurality of second wires form a dedicated transmission path between said first bonding pad and said selected second functional contact pad by way of said first electrically isolated step pad.
