Abstract
A 3D bit cost scalable memory device includes a stack of layers and a via electrode extending vertically through the stack of layers. The layers include a controllable conductivity layer and an electrode layer. The electrode layer has a conductor portion and a separator portion that separates the via electrode from the conductor portion of the electrode layer. At least a storage portion of the controllable conductivity layer is in electrical series between the via electrode and the conductor portion of the electrode layer. The via electrode comprises, for example, tungsten (W). The controllable conductivity layer comprises, for example, an ovonic threshold switch material. The conductor portion of the electrode layer comprises, for example, carbon (C).
