Abstract
In one aspect, the invention relates to logic cells that utilize one or more of spin diodes. By placing one or two control wires on the side of the spin diodes to generate magnetic fields in the spin diodes due to input currents, the logic cell can be changed from one logic gate to another logic gate. The unique feature leads to field logic devices in which simple instructions can be used to construct a whole new set of logic gates.
