Contents Quantitative Logic Assessment Survey-Based Benchmarking Unity Gain Inverter 2-input NAND Gate 32-bit Shift Register Speed, Aerial Footprint, Power Dissipation Performance Projection for 15nm CMOS Tech. Survey-Based Benchmarking Tech. Highlighted for Accelerated Development

Normalized Performance of ERD Devices Figure ERD5 Median delay, energy, and area of proposed devices, normalized to ITRS 15-nm CMOS. (Based on principal investigators’ data; from Rev.

Energy-Delay Product Figure ERD6: Energy versus delay of a NAND2 gate in various post-CMOS technologies. Projections for both high-performance and low-power 15nm CMOS are included as reference. All values are a snapshot in time, and will change as work continues.

Beyond-CMOS Tech. Non-charge Token Figure ERD7: Inverter energy and delay and interconnect delay (*characteristic of transport over 10um) for various beyond-CMOS technologies. Projections for both high-performance and low-power 15nm CMOS included as reference. Solid dots indicate the switch is intrinsically non-volatile. All values are a snapshot in time, and will change as work continues.

Balance between Speed, Area, Interconnect speed Figure ERD8: Transport impact on switch delay, size, and area of control. Circle size is logarithmically proportional to physically accessible area in one delay. Projections for 15nm CMOS included as reference.

Logical Effort Figure ERD9: Estimated logical effort – a measure of the relative “expense” required to perform a given logic function – for new switches in both simple combinatorial and complex circuits (lower values are preferred). Projections for 15nm CMOS included as reference.
