Because:
1. going from 2D to 3D is a one time improvement, not a continuous law that runs for 30 years: at some future point, say a 5nm process becomes 3D, and the number of transistors jumps from N^2 to N^3. That's a single time change.
2. making single atom conventional logic gates is physically impossible: it will have quantum effects and thus will behave like a quantum computer. To make a classical (non-quantum) logic gate, you need at least 8-10 atoms (and that's pushing it).
- janekm 11y agoNo, going from 1xN^2 to 2xN^2 to 3xN^2 and each further stacked layer from there on is still going to be a very major challenge (getting rid of heat being a very major physical challenge for a start). We're already 32 x N^2 for flash packages, but with stacked dies. For flash heat is much easier to manage as only a small part of the die is active at any one time. Stacking memory on top of a cpu core is also common practice in mobile SoCs (though still mostly package-on-package). Going to N^3 from todays M x N^2 is squarely (cubedly? ;)) in the realm of science fiction, there's a lot of space for improvement here.
