Abstract
Magnetoelectronic (ME) logic circuits and methods of operating the same are disclosed for use in energy constrained applications in which logic operations are carried out using a minimal number of physical operations. Microsystems of different circuits made from different types of ME devices can be constructed and employed in applications such as sensors, smart dust, etc. including in clockless applications.
