New graphene-based flash memory writes data in 400 picoseconds, shattering all speed records | "PoX" can execute 25 billion operations every second
To put this achievement into perspective, PoX can perform 25 billion operations per second – surpassing the previous world record for similar technology by a factor of 100,000.
A research team at Fudan University, led by Professor Zhou Peng of the State Key Laboratory of Integrated Chips and Systems, set out to close this performance gap by rethinking the physical structure of flash memory. Rather than using conventional silicon, the researchers turned to graphene – a two-dimensional material celebrated for its remarkable electrical properties – and implemented a Dirac band structure. With its unprecedented speed and low power consumption, PoX could enable real-time processing of massive datasets while also curbing the energy demands of data movement, one of the major inefficiencies in today's AI hardware.
