Charge-Resistance Approach to Benchmarking Performance of Beyond-CMOS Information Processing Devices

Multiple beyond-CMOS information processing devices are presently under active research and require methods of benchmarking them. A new approach for calculating the performance metric, energy-delay product, of such devices is proposed. The approach involves estimating the device properties of resistance and switching charge, rather than dynamic evolution characteristics, such as switching energy and time. The application of this approach to a wide class of charge-based and noncharge-based devices is discussed. The approach suggests pathways for improving the performance of ‘beyond-CMOS’ devices and a new realistic limit for energy-delay product in terms of the Planck’s constant.
