Patent ID: 7489519

Claim:
A ball grid array package comprising: an array of conductive balls; a substrate; an integrated circuit on the substrate; a first bus on the substrate, the first bus including first portions that extend substantially parallel to the integrated circuit, interleaved with second portions that extend substantially toward the integrated circuit, each second portion having an end contiguous with a first portion and another end contiguous with a another first portion; a first set of wires connecting the first bus with a first plurality of nodes on the integrated circuit; a second bus on the substrate, the second bus including first portions that extend substantially parallel to the integrated circuit, interleaved with second portions that extend substantially toward the integrated circuit, each second portion having an end contiguous with a first portion and another end contiguous with another first portion; a second set of wires connecting the second bus with a second plurality of nodes on the integrated circuit; a plurality of pads on the substrate, each of the plurality of pads connected to a respective conductive ball; and a third set of wires each connecting a respective pad to a respective one of a third plurality of nodes on the integrated circuit.
