Abstract: Provided is a phase change RAM. The phase change RAM includes an electrode, a first layer located on the electrode, and a second layer located on the first layer. The first layer includes a locally formed phase change material region. In addition, a method of manufacturing a phase change RAM is provided. The method includes forming an electrode, forming a first layer on the electrode, forming a second layer on the first layer, and forming a phase change material region locally in the first layer due to a voltage applied to the second layer.

Abstract: Provided is a floating gate based 3-terminal analog synapse device including a silicon channel layer; a gate oxide deposited on the silicon channel layer; a charge trap layer deposited on the gate oxide, wherein charges are injected into the charge trap layer; a barrier layer deposited on the charge trap layer, and having lower electron affinity than electron affinity of a material of the charge trap layer; and a gate metal layer deposited on an upper surface of the barrier layer, wherein a gate voltage is applied to the gate metal layer.

Abstract: Electrical switching technologies employ the otherwise undesirable line defect in crystalline materials to form conductive filaments. A switching cell includes a crystalline layer disposed between an active electrode and another electrode. The crystalline layer has at least one channel, such as a line defect, extending from one surface of the crystalline layer to the other surface. Upon application of a voltage on the two electrodes, the active electrode provides metal ions that can migrate from the active electrode to the other electrode along the line defect, thereby forming a conductive filament. The switching cell can precisely locate the conductive filament within the line defect and increase the device-to-device switching uniformity.
