N2 - In this paper, we propose a highly reliable and anti-cloning STT-MRAM reconfigurable physical unclonable function (PUF) chip. To improve reliability, a charge-injection offset-compensation sense amplifier (CIOC-SA) with a low input offset of 5.6 mV is proposed, which significantly reduces the worst-case Bit Error Rate (BER) from 0.146% to 0.0025%. To enhance anti-clonality, two innovations are proposed, including a novel STT-MRAM-based PUF reconfiguration scheme and an ultra-low-cost invasive-attack detection scheme. The reconfiguration scheme achieves a near-ideal reconfiguration hamming distance of 0.456. Featuring a low wordline (WL) voltage and a two-stage hysteresis comparator configured from the CIOC-SA, the proposed detection scheme achieves high detection accuracies of 90.4%, 88.6%, and 99.3% for three test PUF arrays emulating different levels of invasive attacks, demonstrating a notably enhanced anti-clonality with ultra-low cost in latency and area.
