Non-volatile Flash-based memory devices, which incorporate a novel redox-active diruthenium molecule, is demonstrated. The memory device is in a capacitor structure, metal/oxide/molecule/oxide/silicon, where the diruthenium molecule is covalently attached to the oxide using a unique “click” chemistry attachment which serves two fold purposes: (1) ease of chemical design and synthesis, and (2) provides an additional spatial barrier between the oxide/silicon to the diruthenium molecule. The molecular memory devices display an unsaturated charge storage window, and we attribute this demonstration to the intrinsic properties of the redox-active molecule. These molecular devices are very attractive for future non-volatile memory applications.
