Abstract:
A dramatically new principle for making nanoscale electronic memories has been demonstrated by a team of US researchers. In their so-called NanoCells, connections between electrodes are made at random through electrically conducting and switchable molecules. James Tour of Rice University in Houston, Texas, and co-workers say that NanoCells have voltage-switchable memory states that persist for over a week at room temperature. Even though the junctions in these devices are forged from organic molecules, the memory states seem capable of withstanding at least short-term exposure to air.
