Abstract: A MLU-based magnetic device including a plurality of MLU-based magnetic cells, each MLU cell including a first ferromagnetic layer having a first magnetization, a second ferromagnetic layer having a second magnetization, and a spacing layer between the first and second ferromagnetic layers. An input device is configured for generating an input signal adapted for changing the orientation of the first magnetization relative to the second magnetization and vary a resistance of the MLU device. A bit line is configured for passing a sense signal adapted for measuring the resistance. A processing unit is configured for computing an electrical variation from the sense signal and outputting an electrical variation signature. The present disclosure further pertains to an authentication method for reading the MLU device.
