Highly reliable memory-based physical unclonable function using spin-transfer torque MRAM

In recent years, Physical Unclonable Function (PUF) based on the inimitable and unpredictable disorder of physical devices has emerged to address security issues related to cryptographic key generation. In this paper, a novel memory-based PUF based on Spin-Transfer Torque (STT) Magnetic RAM, named a...
