  • Patent number: 10943952
    Abstract: The switching device includes three terminals including an inner surface, an oxide layer on the inner surface of the third terminal, and a chalcogenide pillar extending through the oxide layer and the third terminal, the pillar being in electrical communication with the first terminal and the second terminal, wherein the voltage difference between the first terminal and the second terminal changes the channel from a first state to a second state when a threshold voltage between the first terminal and the second terminal is exceeded, the threshold voltage being dependent on temperature. The third terminal is resistive and receives a control signal to apply heat to the pillar and modulate the threshold voltage. The switching device can be used to select the memory stack through the bitline and provide a nearly limitless current based on the threshold switching conduction providing avalanche current conduction through the switching device.

  • Publication number: 20180294234
    Abstract: Module and method of a selective electronic-magnetic interference shielding includes a substrate, at least a first electronic element deployed on a principle surface of the substrate, an mold resin covering the first electronic element, and an electronic-magnetic interference shielding, wherein the mold resin has a mold surface relatively far above the substrate and is divided into a central area and an outer area surrounding the central area. The mold resin installs a trench between the central area and the outer area, the trench forms a closed route enfolding the first electronic element, and the electro-magnetic interference shielding distributes over the central area and the trench. Therefore the module and method of a selective electronic-magnetic interference shielding is adaptable to various required designs with lower manufacturing cost.
