摘要： A chalcogenide material and chalcogenide memory device exhibiting fast operation (short set pulse times) over an extended range of reset state resistances. Electrical devices containing the instant chalcogenide materials permit rapid transformations from the reset state to the set state for reset and set states having a high resistance ratio. The instant devices thus provide for high resistance contrast and improved readability of memory states while preserving fast operational speeds for the device. 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. In one embodiment, the atomic concentration of Ge is between 11% and 22%, the atomic concentration of Sb is between 22% and 65%, and the atomic concentration of Te is between 28% and 55%. In a preferred embodiment, the atomic concentration of Ge is between 15% and 18%, the atomic concentration of Sb is between 32% and 35%, and the atomic concentration of Te is between 48% and 51%.

摘要： A carbon containing layer may be formed between a pair of chalcogenide containing layers of a phase change memory. When the lower chalcogenide layer allows current to pass, a filament may be formed therein. The filament then localizes the electrical heating of the carbon containing layer, converting a relatively localized region to a lower conductivity region. This region then causes the localization of heating and current flow through the upper phase change material layer. In some embodiments, less phase change material may be required to change phase to form a phase change memory, reducing the current requirements of the resulting phase change memory.
