    摘要: Non-volatile resistive-switching memories formed using anodization are described. A method for forming a resistive-switching memory element using anodization includes forming a metal containing layer, anodizing the metal containing layer at least partially to form a resistive switching metal oxide, and forming a first electrode over the resistive switching metal oxide. In some examples, an unanodized portion of the metal containing layer may be a second electrode of the memory element.

    摘要: This disclosure provides a method of fabricating a semiconductor device layer and an associated memory cell. Empirical data may be used to generate a hysteresis curve associated with deposition for a metal-insulator-metal structure, with curve measurements reflecting variance of an electrical property as a function of cathode voltage used during a sputtering process. By generating at least one voltage level to be used during the sputtering process, where the voltage reflects a suitable value for the electrical property from among the values obtainable in mixed-mode deposition, a semiconductor device layer may be produced with improved characteristics and durability. A multistable memory cell or array of such cells manufactured according to this process can, for a set of given materials, be fabricated to have minimal leakage or “off” current characteristics (Ileak or Ioff, respectively) or a maximum ratio of “on” current to “off” current (Ion/Ioff).

    摘要: A resistance-change memory device using stress engineering is described, including a first layer including a first conductive electrode, a second layer above the first layer including a resistive-switching element, a third layer above the second layer including a second conductive electrode, where a first stress is created in the switching element at a first interface between the first layer and the second layer upon heating the memory element, and where a second stress is created in the switching element at a second interface between the second layer and the third layer upon the heating. A stress gradient equal to a difference between the first stress and the second stress has an absolute value greater than 50 MPa, and a reset voltage of the memory element has a polarity relative to a common electrical potential that has a sign opposite the stress gradient when applied to the first conductive electrode.
