Abstract
A standard memory chip () is vertically assembled with two processor chips () of split architecture by means of a small silicon interposer () stacked onto a large silicon interposer (); both interposers include through-silicon vias (TSVs), while the chips are free of TSVs. The TSVs of small interposer () connect to the memory chip () and to the bottom interposer (). Symmetrically positioned relative to interposer (), and connected to it by short signal traces, chips () are attached to the TSVs of interposer, which in turn is attached to a substrate () with supply connections.
