    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 non-volatile memory element includes a first interlayer insulation layer 11 having a first through-hole 11a, a second interlayer insulation layer 12 having a second through-hole 12a formed on the first interlayer insulation layer 11, a bottom electrode 13 provided in the first through-hole 11, recording layer 15 containing phase change material provided in the second through-hole 12, a top electrode 16 provided on the second interlayer insulation layer 12, and a thin-film insulation layer 14 formed between the bottom electrode 13 and the recording layer 15. In accordance with this invention, the diameter D1 of a bottom electrode 13 buried in a first through-hole 11a is smaller than the diameter D2 of a second through-hole 12a, thereby decreasing the thermal capacity of the bottom electrode 13. Therefore, when a pore 14a is formed by dielectric breakdown in a thin-film insulation layer 14 and the vicinity is used as a heating region, the amount of heat escaping to the bottom electrode 13 is decreased, resulting in higher heating efficiency.

    摘要: A method of programming an electrical variable resistance memory device. When applied to variable resistance memory devices that incorporate a phase-change material as the active material, the method utilizes a plurality of crystalline programming states. The crystalline programming states are distinguishable on the basis of resistance, where the resistance values of the different states are stable with time and exhibit little or no drift. As a result, the programming scheme is particularly suited to multilevel memory applications. The crystalline programming states may be achieved by stabilizing crystalline phases that adopt different crystallographic structures or by stabilizing crystalline phases that include mixtures of two or more distinct crystallographic structures that vary in the relative proportions of the different crystallographic structures. The programming scheme incorporates at least two crystalline programming states and further includes at least a third programming state that may be a crystalline, amorphous or mixed crystalline-amorphous state.
