An NML in-plane Wire Crossing Structure

Abstract

The Nanomagnetic Logic (NML) is a promising new technology to build low-power devices at room temperature. Furthermore, this technology allows mixing logic and memory on the same device, providing area and power consumption optimizations. However, when designing complex nanomagnetic circuits, we often need to cross wires without needing to include extra layers of interacting nanomagnets that would make the synthesis process more complex. In this work, we propose and analyze the behavior of a new structure that allows an in-plane wire crossing that can be useful in designing complex NML circuits. The design was built based on a clocking scheme of 4 phases and simulated using the Landauer-Lifshitz-Gilbert equation through the NMLSim v2 simulator. Our design can implement horizontal and vertical wire crossings without any extra time delay by exploring the time-division multiplexing method.
