N2 - In this work, we present highly reliable operations of physical unclonable function (PUF) using the pristine state of Al2 O3/TiOx memristor crossbar arrays. The device stack is optimized in terms of stoichiometry and thickness to obtain temperature-independent I-V properties. A strong PUF with a large ( sim 10 {17}) number of challenge-response pairs is demonstrated based on the crossbars, and the bit-error rate (BER) was experimentally verified less than 1% (0.896% at 80 °C) without correction methods thanks to tunneling conduction. In addition, the uniformity, diffuseness, and uniqueness of the PUF are evaluated 50%, and its randomness is verified through both NIST tests and machine learning attacks, confirming robust security property.
