- Non-Commutative Rough 3D-Integration Dynamics (NC-R3DI) Subsuming Sub-2nm Microfabrication and HBM 3D Packaging Limits via UROA, STCT, and RQIG
Sub-2nm logic scaling and High Bandwidth Memory (HBM) 3D packaging are inextricably coupled system limits. While lithography and atomic etching govern transistor power bounds, HBM stacking dictates severe thermal and memory wall constraints. This paper supersedes independent…
