IBM Stacks Transistors Vertically to Push Past 1-Nanometer Limits
IBM announced a prototype chip packing nearly 100 billion transistors into a fingernail-sized area. The design uses a new “nanostack” architecture that stacks transistors in two layers instead of shrinking them only on a flat plane. The result nearly doubles the density of the company’s 2-nanometer chip from 2021 and points to performance gains or […]
