An exemplary memory device includes a first dielectric layer with a first conductive contact therein. A phase change material (PCM) is disposed on top of the first dielectric layer and provided with an insulating layer integrally on a top surface of the PCM. A first electrode is disposed over the first dielectric layer and covered a portion of the first conductive contact and the insulating layer in a first direction, contacting to the first conductive contact and a first side of the PCM. A second electrode is disposed over the first dielectric layer and covered a portion of the insulating layer in a second direction, contacting to a second side of the PCM. A second dielectric layer is disposed over the first dielectric layer to cover the first electrode, the second electrode, the insulating layer and the PCM, including a second conductive contact connected to the second electrode.
