- Memristor based on graphene, tungsten, and hafnium oxide operates over 700°C, reducing cooling needs in extreme environments.
- Device stores data for over 50 hours at 1.5V, withstands >10^9 cycles, and switches in tens of nanoseconds.
- Graphene prevents tungsten migration and short-circuiting, enabling high-temperature tolerance via unique surface chemistry.
- Applications include space exploration, geothermal drilling, nuclear plants, and AI accelerators for energy-efficient computing.
- Research led to unexpected discovery; future work aims to integrate with logic devices and scale through startup Tetramem Inc.
