Brown University: Research on Computational Nanotechnology

As the feature sizes of chips shrink to the nanometer level new devices, methods of assembly, and architectures are being investigated. The crossbar, an old idea, is expected to play a prominent role in these new developments; its regular structure is well suited to nanotechnology-based assembly. A nanometer-scale crossbar is useful only if wires in each of its dimensions can be addressed individually. Given the small dimensions involved, every method proposed to address nanowires involves stochastic assembly. Our research examines methods of stochastic addressing of nanowires as well as the efficient data storage in crossbar-based memories.
