Abstract
- Spin logic devices based on domain wall (DW) motion offer flexible architectures to store and carry logic information in a circuit. In this device concept, information is encoded in the magnetic state of a magnetic track shared by multiple magnetic tunnel junctions (MTJs) and is processed by DW motion. Here, we demonstrate that all-electrical control of such nanoscale DW-based logic devices can be realized using a novel MTJ stack. In addition to field-driven motion, which is isotropic, we show the directional motion of DWs driven by current, a key requirement for logic operation. Full electrical control of an AND logic gate using DW motion is demonstrated. Our devices are fabricated in imec’s 300-mm CMOS fab on full wafers, which clears the path for large-scale integration. This proof of concept, thus, offers potential solutions for high-performance and low-power DW-based devices for logic and neuromorphic applications. [ABSTRACT FROM AUTHOR]
