摘要： A ring shaped heater surrounds a chalcogenide region along the length of a cylindrical solid phase portion thereof defining a change phase memory element. The chalcogenide region is formed in a sub-lithographic pore, so that a relatively compact structure is achieved. Furthermore, the ring contact between the heater and the cylindrical solid phase portion results in a more gradual transition of resistance versus programming current, enabling multilevel memories to be formed.

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： An electronic device and method of programming for binary and multilevel memory operation. The active material of the device is a phase-change material. The method includes utilization of the pulse duration of electrical pulses as a programming variable to program a phase-change device to two or more memory states that differ in the relative proportion and/or spatial arrangement of crystalline and amorphous phase regions. Pulse width programming, in conjunction with a device electrical contact having a resistivity within a particular range, enables fine control over the crystalline-amorphous phase-change process by facilitating control over the spatial distribution of thermal energy produced by Joule heating. The degree of control over the phase-change process enables reliable multilevel memory operation by providing for reproducible programming of memory states that are well-resolved in both resistance and programming variable.
