With an ever-increasing globalization of the semiconductor chip manufacturing supply chain coupled with soaring complexity modern-day integrated circuits (ICs), intellectual property (IP) piracy, reverse engineering, counterfeiting, and hardware trojan insertion have emerged as severe threats that compromised security critical components. Logic locking (LL) is IP protection technique can mitigate these by a given IC secret key. Earlier LL demonstrations based on traditional silicon complementary metal-oxide-semiconductor (CMOS) technology emerging memristors require significant investment in form additional input gates extensive CMOS peripherals, rendering them area- energy-inefficient. In this article, we demonstrate multiple two-dimensional (2D) nanoscale memtransistor-based programmable logic such AND, NAND, OR, XOR, NOT gates, each which be locked/unlocked without requiring peripherals at minuscule energy expenditure (<1 pJ). We also show SAT-solver unsuccessful breaking into any ISCAS'85 benchmark utilize our scheme. The massive resilience to SAT-attack attributed prowess 2D memtransistors enable device-level all circuits. Given transistors are drawing increasing attention corporations like Intel, TSMC, etc., replace and/or augment aggressively scaled nodes, demonstration energy-efficient considered step toward realization secure ICs enabled memtransistors.
