  • Patent number: 8129250
    Abstract: A resistor with improved switchable resistance and a non-volatile memory device includes a first electrode, a second electrode facing the first electrode and a resistance structure between the first electrode and the second electrode. The resistance structure includes an insulating dielectric material in which a confined switchable conductive region is formed between the first and second electrode. The resistor further includes a perturbation element, locally exerting mechanical stress on the resistance structure in the vicinity of the perturbation element at least during a forming process in which the confined switchable conductive region is formed.

  • Patent number: 6815744
    Abstract: A microelectronic device is designed such that it includes a region between electrodes having a switchable ohmic resistance wherein the region is made of a substance comprising components Ax, By, and oxygen Oz. The ohmic resistance in the region is reversibly switchable between different states by applying different voltage pulses. The different voltage pulses lead to the respective different states. An appropriate amount of dopant(s) in the substance improves the switching, whereby the microelectronic device becomes controllable and reliable.
