Patent ID: 7948071

Claim:
An assembly including a plurality of memory dies within a package, the assembly comprising: a substrate including a plurality of contact pads formed on a surface thereof; a first memory die having a first side and a second side, the second side facing the surface of the substrate, the first memory die having at least two memory array portions formed therein, the first side including a plurality of bond pads formed in a center region between the memory array portions, the first memory die further including a redistribution layer that includes re-routing lines that electrically couple the bond pads to re-routed bond pads in a periphery region of the first memory die; a first plurality of wires electrically coupling the re-routed bond pads of the first memory die to a first set of the plurality of contact pads of the substrate; a second memory die having a first side and a second side, the second side facing the surface of the substrate, the second memory die having at least two memory array portions formed therein, the first side including a plurality of bond pads formed in a center region between the memory array portions, the second memory die further including a redistribution layer that includes re-routing lines that electrically couple the bond pads to re-routed bond pads in a periphery region of the second memory die; a second plurality of wires electrically coupling the re-routed bond pads of the second memory die to a second set of the plurality of contact pads of the substrate, wherein more than half of the first and second sets of the plurality of contact pads are electrically coupled to both the re-routed bond pads of the first memory die and the re-routed bond pads of the second memory die; and wherein the redistribution layer of each of the first and second memory dies includes a ground plane, the ground plane including a line in the periphery region substantially encircling all of the bond pads and a plurality of ground lines between at least some of the re-routing lines.
