The memory wall — the widening gap between processor throughput and memory bandwidth — has become the defining hardware constraint of the artificial intelligence era, now compounded by a structural NAND flash supply crisis driven by AI demand. We propose a post-transistor, pre-quantum memory architecture built on single-layer fluorographane (CF), in which the bistable covalent orientation of each fluorine atom relative to the sp³-hybridized carbon scaffold constitutes an intrinsic, radiation-hard binary degree of freedom. The C–F inversion barrier of ~6.6 eV (B3LYP-D3BJ/def2-TZVP, this work; rigorous lower bound) yields a thermal bit-flip rate of ~10⁻⁹⁸ s⁻¹ and a quantum tunneling rate of ~10⁻⁹³ s⁻¹ at 300 K, simultaneously eliminating both spontaneous bit-loss mechanisms. A single 1 cm² sheet encodes 447 TB of non-volatile information at zero retention energy. Volumetric nanotape architectures extend this to 0.4–9 ZB/cm³. We present a tiered read-write architecture progressing from scanning-probe validation through near-field mid-infrared arrays to a dual-face parallel configuration governed by a central controller, targeting 25 PB/s aggregate throughput. A scanning-probe prototype — constructible from commercially available laboratory instrumentation — already constitutes a functional non-volatile memory device with areal density exceeding all existing technologies by more than five orders of magnitude.
