Abstract
MRAM-based physical unclonable function (PUF) design has become a hot research topic in academia and industry. The spin-orbit torque-based PUFs (SOT-PUFs) have the advantages of non-volatility, substantial miniaturization, and low energy consumption. However, existing MRAM PUFs share a common issue: PUF and memory functions cannot coexist simultaneously in the same array. Meanwhile, most of the memory-based PUFs are weak PUFs. The proposed multi-functional design further improves these issues with memory and strong PUF functionality where NAND-like SOT devices further reduce cell area. The uniformity and uniqueness are estimated to be 0.4986 and 0.4997, respectively. Our work validates the multi-functionality of the proposed design and paves the way for SOT-based applications.
