本文研究了基于非易失性存储器（eNVM）技术（自旋转移力矩磁随机存取存储器、相变RAM和电阻式RAM）的基于存储器的物理不可克隆功能（MemPUF）的可行性和质量。使用这三种技术的MemPUF在可靠性、唯一性和随机性方面进行了评估，使用不同的传感模式和不同的操作条件。我们的研究结果表明，基于eNVM的MemPUF差分传感模式具有良好的随机性和可靠性。与传统的MemPUF相比，基于eNVM的MemPUF在面积成本方面更好。
The feasibility and quality of Memory-based Physical Unclonable Functions (MemPUFs) based on emerging Non-Volatile Memory (eNVM) technologies (Spin-Transfer Torque Magnetic Random Access Memory, Phase Change RAM, and Resistive RAM) are studied in this paper. MemPUFs using the three technologies were evaluated in terms of reliability, uniqueness and randomness using different sensing modes and under varying operating conditions. Our results show that eNVM based MemPUFs with differential sensing mode exhibit good randomness and reliability. As compared to conventional MemPUFs, eNVM based MemPUFs are better in terms of area cost.
