Beyond CMOS

[5] Beyond CMOS is the name of one of the 7 focus groups in ITRS 2.0 (2013) and in its successor, the International Roadmap for Devices and Systems.

[8] The 2014 benchmarking included 11 electronic, 8 spintronic, 3 orbitronic, 2 ferroelectric, and 1 straintronics technology.

[8] The 2015 ITRS 2.0 report included a detailed chapter on Beyond CMOS,[9] covering RAM and logic gates.

One variant called rapid single-flux quantum (RSFQ) logic was considered promising by the NSA in a 2005 technology survey despite the drawback that available superconductors require cryogenic temperatures.

More energy-efficient superconducting logic variants have been developed since 2005 and are being considered for use in large scale computing.
