    摘要: Memory devices and methods for operating such devices are described which can effectively program the metal-oxide memory elements in an array, while also avoiding applying unnecessarily high voltage pulses. Programming operations described herein include applying a lower voltage pulse across a metal-oxide memory element to establish a desired resistance state, and only applying a higher voltage pulse when the lower voltage pulse is insufficient to program the memory element. In doing so, issues associated with applying unnecessarily high voltages across the memory element can be avoided.

    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 resistance memory cell is provided and includes a first electrode, a tungsten metal layer, a metal oxide layer, and a second electrode. The tungsten metal layer is disposed on the first electrode. The metal oxide layer is disposed on the tungsten metal layer. The second electrode includes a first connection pad, a second connection pad, and a bridge portion electrically connected between the first connection pad and the second connection pad. The bridge portion is disposed on the metal oxide layer or surrounds the metal oxide layer. The resistance memory cell adjusts a resistivity of the metal oxide layer through a first current path, passing through the metal oxide layer and the tungsten metal layer, or a second current path extending from the first connection pad to the second connection pad.

    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.
