In this book, we present studies on nanoscale resistance switching devices (memristive devices). The devices show excellent resistance switching properties such as fast switching time, high on/off ratio, good data retention and high endurance. As digital memory devices, the devices are ideally suited in a crossbar architecture which offers ultra-high density and intrinsic defect tolerance capability. As an example, a high-density 1kb crossbar memory was demonstrated, proving its promising aspects for memory and reconfigurable logic applications. Furthermore, we demonstrated that the devices...
