Scientists develop 447 TB/cm² atomic memory using fluorographane
Original: 447 TB/cm² at zero retention energy – atomic-scale memory on fluorographane
Researchers propose fluorographane-based memory achieving 447 terabytes per square centimeter with zero retention energy. The atomic-scale memory uses fluorine atom orientation as binary storage, offering thermal bit-flip rates of 10^-65 s^-1 at room temperature.
Scientists led by Ilia Toli developed a post-transistor memory architecture using single-layer fluorographane (CF), where each fluorine atom's covalent orientation creates a binary storage bit. The C-F inversion barrier of 4.6 eV provides exceptional stability with thermal bit-flip rates of 10^-65 s^-1 and quantum tunneling rates of 10^-76 s^-1 at 300K. A single 1 cm² sheet stores 447 TB without retention energy, while volumetric nanotape configurations could reach 0.4-9 zettabytes per cubic centimeter. The research proposes a tiered read-write system from scanning-probe validation to mid-infrared arrays, projecting 25 PB/s throughput. The prototype already exceeds existing memory density by five orders of magnitude, addressing the memory wall constraint limiting AI hardware performance amid NAND flash supply shortages.
