    摘要： A method comprising forming a sacrificial layer over less than the entire portion of a contact area on a substrate, the sacrificial layer having a thickness defining an edge over the contact area, forming a spacer layer over the spacer, the spacer layer conforming to the shape of the first sacrificial layer such that the spacer layer comprises an edge portion over the contact area adjacent the first sacrificial layer edge, removing the sacrificial layer, while retaining the edge portion of the spacer layer over the contact area, forming a dielectric layer over the contact area, removing the edge portion, and forming a programmable material to the contact area formerly occupied by the edge portion. An apparatus comprising a volume of programmable material, a conductor, and an electrode disposed between the volume of programmable material and the conductor, the electrode having a contact area at one end coupled to the volume of programmable material, wherein the contact area is less than the surface area at the one end.

    摘要： A memory cell may include a phase-change material. Adhesion between the phase-change material and a dielectric or other substrate may be enhanced by using an adhesion enhancing interfacial layer. Conduction past the phase-change material through the interfacial layer may be reduced by providing a discontinuity or other feature that reduces or prevents conduction along said interfacial layer.

    摘要： A high security cylinder lock includes a housing comprising a plurality of driver pin bores for disposing spring loaded driver pins; a plug rotatable within the housing comprising a plurality of balancing pin bores for disposing spring loaded balancing pins and a plurality of combination pin bores for disposing combination pins. Each combination pin is sandwiched between a driver pin and a balancing pin. The extension force of the balancing spring at its pre-load length is greater than the extension force of the driver spring at its fully-load length. The compound force causes at least one combination pin partially extended into a corresponding driver pin bore in the housing when the plug is at its first rotational orientation in case of no key engaged. The key profile pushes the balancing pins to move to such position that all mating surfaces of the combination pins and the driver pins to lies onto the shear line of the lock. The balancing pin, balancing spring and balancing spring seal set may be substituted by magnetic balancing pin and magnetic seal pin set.
