The Alternative Computing Group at NIST has an ongoing program in developing prototype circuits and designing new architectures for neuromorphic computing utilizing exotic devices such as metal-oxide and phase-change memristors, magnetic tunnel junctions, and Josephson junctions. These devices are combined with custom-designed conventional CMOS circuits to realize diverse functionalities, from crossbar-based machine learning to race-logic-based DNA sequencing. Opportunities exist for experimental work in device fabrication and measurement using NIST’s state-of-the-art NanoFab and extensive measurement capabilities, CMOS circuit design work for foundry tape-out, and theoretical work developing new algorithms and architectures that leverage the low-energy, high-speed properties of emerging devices. The ultimate goal is to explore the landscape of emerging hardware-based artificial intelligence systems to better understand the role played by measurement and metrology in these complex, adaptive systems.
