System-level energy and performance projections for nanomagnet-based logic

This paper examines how realistic implementations of the drive circuitry needed to control circuit elements made from nano-scale magnets can affect system-level energy and performance. Expected non-uniform clock fields, clock field discontinuities and out-of-plane fields are all considered. We find that realistic fabrication mechanisms should not inhibit logical correctness and that this technology appears capable of outperforming low power CMOS equivalents with similar energy requirements — and paths to additional energy savings exist.
