NVM-based PUFs offer secure authentication and cryptographic applications by exploiting NVMs' MLC to generate diverse, ML-attack-resistant responses. Yet, frequent writes degrade these PUFs, lowering reliability and lifespan. This paper presents a model to assess endurance effects on NVM PUFs, guiding the creation of more robust PUFs. Our novel NVM PUF design enhances endurance by evenly distributing writes, thus mitigating cell stress, achieving a 62x improvement over current solutions while preserving security against learning-based attacks.
