nanomechanisms are employed in nanomemory elements which , in turn , are employable in nanoscale memory devices . a nanoscale particle is enclosed within a nonocapsule to create a bistable device which is both readable and writable in a variety of ways . a nonamechanism for use in a nanoscale memory element includes a first element in the form of a nanoassembly having a cavity and second element in the form of a nanostructure which is removeably disposed within the cavity . in one embodiment , the nanoassembly is demonstrated as a c 480 capsule and the nanostructure is demonstrated as a charged hd 60 fullerene molecule . the nanoscale memory devices combine high switching speed , high packing density and stability with non0volatility of the stored data .
