Project TitleMagnetic Diode Based Programmable Logic
Track Code2011-023
Short Description

Magnetoresistive semiconductor heterojunctions to create a complete transistor and diode logic family that is superior to CMOS due to its smaller number of devices, reduced power and high frequency

Magnetic semiconductor devices are used as building blocks for programmable logic architecture. Using magnetic diodes and transistors Northwester researchers have shown the possibility of programmable gates. Changing a gate using magnetic fields that are generated using currents creates many unique capabilities. One such capability is the possibility of an inversion operation using a diode. Diode logic using conventional semiconductor devices is incomplete as none of the inverted gates can be achieved. They show the possibility of a complete logic using one or more of these magnetic diodes.
