IBM's nanostack is a chip architecture that stacks multiple layers of transistors vertically to increase transistor density and computing power within a smaller physical footprint. This 3D approach enables more efficient use of chip space compared to traditional flat, 2D designs. The technology represents IBM's research into advanced semiconductor manufacturing techniques to overcome limitations of conventional chip scaling.
