    摘要: This invention provides novel high density memory devices that are electrically addressable permitting effective reading and writing, that provide a high memory density (e.g., 1015 bits/cm3), that provide a high degree of fault tolerance, and that are amenable to efficient chemical synthesis and chip fabrication. The devices are intrinsically latchable, defect tolerant, and support destructive or non-destructive read cycles. In a preferred embodiment, the device comprises a fixed electrode electrically coupled to a storage medium comprising a storage molecule comprising a first subunit and a second subunit wherein the first and second subunits are tightly coupled such that oxidation of the first subunit alters the oxidation potential(s) of the second subunit rendering the oxidation potential(s) of the second unit different and distinguishable from the oxidation potentials of the first subunit.
