CryoCache: A Fast, Large, and Cost-Effective Cache Architecture for Cryogenic Computing

Cryogenic computing, which is to run a computer at extremely low temperatures (e.g., 77K), is a highly promising solution to dramatically improve the computer's performance and power efficiency thanks to the significantly reduced leakage power and wire resistance. However, computer architects are facing fundamental challenges in developing and deploying cryogenic-optimal architectural units due to the lack of understanding about its cost-effectiveness and feasibility (e.g., device and cooling costs vs. speedup, energy and area saving) and thus how to architect such cryogenic-optimal units.
