摘要： A self-aligning stacked memory cell array structure and method for fabricating such structure. The memory cell array includes a stack of memory cells disposed adjacent to opposing sides of a conductive line that is formed within a trench. The memory cells are stacked such that the memory element surface of each memory cell forms a portion of the sidewall of the conductive line. The conductive line is formed within the trench such that electrical contact is made across the entire memory element surface of each memory cell. Such structure and method for making such structure is a self-aligning process that does not require the use of any additional masks.

摘要： A method of programming a phase change device includes selecting a desired threshold voltage (Vth) and applying a programming pulse to a phase change material in the phase change device. The applying of the programming pulse includes applying a quantity of energy to the phase change material to drive at least a portion of this material above a melting energy level. A portion of the energy applied to the phase change material is allowed to dissipate below the melting energy level. The shape of the energy dissipation from the phase change material is controlled until the energy applied to the phase change material is less than a quenched energy level, to cause the phase change device to have the desired Vth. A remaining portion of the energy applied to the phase change material is allowed to dissipate to an environmental level.

摘要： Memory devices described herein are programmed and erased by physical segregation of an electrically insulating layer out of a memory material to establish a high resistance state, and by re-absorption of at least a portion of the electrically insulating layer into the memory material to establish a low resistance state. The physical mechanism of programming and erasing includes movement of structure vacancies to form voids, and/or segregation of doping material and bulk material, to create the electrically insulating layer consisting of voids and/or dielectric doping material along an inter-electrode current path between electrodes.

摘要： A phase change memory device and a method for programming the same. The method includes determining a characterized lowest SET current and corresponding SET resistance for the phase change memory device. The method includes determining a characterized RESET current slope for the phase change memory device. The method also includes calculating a first current amplitude for a RESET pulse based on the characterized lowest SET current and the characterized RESET current slope. The method includes applying the RESET pulse to a target memory cell in the phase change memory device and measuring the resistance of the target memory cell. If the measured resistance is substantially less than a target resistance, the method further includes applying one or more additional RESET pulses. In one embodiment of the invention, the one or more additional RESET pulses have current amplitudes greater than a previously applied RESET pulse.
