Flip-flops are data storage elements used in integrated circuits. And while flip-flops are good, non-volatile flip-flops are even better! The latest generation of magnetic tunnel junctions (MTJs), known as spin-orbit torque (SOT) MTJs, could be the key, delivering crucial speed, energy efficiency, and robustness.

Researchers at Spintec created a model of the SOT-MTJs for the development of new circuit architectures. And the SOT-MTJs are four times faster and use twenty times less energy than spin-transfer torque (STT) MTJs.

These results have yet to be confirmed by a demonstrator that will be tested in June. The research was carried out under the EU-funded SPOT project, which Spintec is leading and in which Leti and Karlsruhe Institute of Technology (KIT) are participating.
