Your stacking example uses logic, but for cost-conscious memory, shouldn't there be concern?

While alternatives to lithography challenges is one value prop for 3D, there is also the issue of package connectivity that will force one to adopt stacking chips. The intra-processor communication (IPC) and/or inter chip to chip communication pipelines at higher data rates (40/100Gig) using differential signaling is already congesting the server / switch mother boards. 3D will be a good answer as long as thermal and power management issues are addressed.

Good question resistion. With it's rich vertical connectivity (vertical interconnect density ~ horizontal interconnect density) and shorter wires, we can remove many of the repeater buffers and as well as make smaller drivers between subcircuits. A logic chip would be 2 layers of 25% the size (50mm2 2D becomes 2x12mm2 in m3D). See one calculation at http://www.monolithic3d.com/why-monolithic-3d.html . Another ref is L. Zhou, et al., “Implementing a 2-Gbs 1024-bit ½-rate low-density parity-check code decoder in three-dimensional integrated circuits”, Proc. ICCD, 2007. It about one node of scaling.

3D is probably one of the better options, but is it actually cheaper? It is still cost-additive per layer/plane, isnt' it?
