摘要： A method of programming a multi-layer chalcogenide electronic device. The device includes an active region in electrical communication with two terminals, where the active region includes two or more layers. The method includes providing an electrical signal between the two terminals, where the electrical signal alters an electrical characteristic of a layer remote from one of the terminals. In one embodiment, the layer remote from the terminal is a chalcogenide material and the electrical characteristic is resistance. In another embodiment, an electrical characteristic of the layer in contact with the terminal is also altered. The alteration of an electrical characteristic may be caused by a transformation of a chalcogenide material from one structural state to another structural state.

摘要： A chalcogenide material and chalcogenide memory device having less stringent requirements for formation, improved thermal stability and/or faster operation. The chalcogenide materials include materials comprising Ge, Sb and Te in which the Ge and/or Te content is lean relative to the commonly used Ge2Sb2Te5 chalcogenide composition. Electrical devices containing the instant chalcogenide materials show a rapid convergence of the set resistance during cycles of setting and resetting the device from its as-fabricated state, thus leading to a reduced or eliminated need to subject the device to post-fabrication electrical formation prior to end-use operation. Improved thermal stability is manifested in terms of prolonged stability of the resistance of the device at elevated temperatures, which leads to an inhibition of thermally induced setting of the reset state in the device. Significant improvements in the 10 year data retention temperature are demonstrated. Faster device operation is achieved through an increased speed of crystallization, which acts to shorten the time required to transform the chalcogenide material from its reset state to its set state in an electrical memory device.
