Abstract
A cross-point array device includes a substrate, a first conductive line disposed over the substrate and extending in a first direction, a plurality of pillar structures disposed on the first conductive line, each of the pillar structure comprising a memory electrode, a resistive memory layer disposed along surfaces of the pillar structures, a threshold switching layer disposed on the resistive memory layer, and a second conductive line electrically connected to the threshold switching layer and extending a second direction that is not parallel to the first conductive line.
