Abstract
We design a spintronic physical unclonable function (PUF) based on sub-100 nm voltage-controlled magnetic anisotropy hybrid magnetic tunnel junctions (VCMA-MTJs). This complementary metal-oxide-semiconductor VCMA-MTJ (CMOS/VCMA-MTJ) PUF architecture was evaluated by combining micromagnetic simulations, Verilog-A modeling, and circuit-level simulations. The PUF architecture, comprising four 16 rows x 16 columns arrays, demonstrates effective read and write operations using conventional voltage sensing that are orders of magnitudes lower than previous spintronic-based PUFs. This study proves the potential of the proposed solution in security applications based on hardware authentication.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
