A collaboration between labs in UCLA and the California Institute of Technology has recently published an article in Nature decribing a 160-kilobit memory device using these molecular switches in combination with nanowire meshes to create controllable electronic environments. Nanowires are similar to nanotubes, except that they may consist of materials other than carbon - in this case Silicon and Titanium - that may result in unique conductive properties. In this device, the silicon and titanium nanowires cross eachother in a checkerboard pattern (see figure) with bistable molecules at each intersection. Manipulation of each nanowire controls the state of each switch and serves as a miniscule bit of memory on the order of 100 billion bits per square centimeter.
