Phase Change Memory with Chalcogenide Selector (PCMS): Characteristic Behaviors, Physical Models and Key Material Properties

  • Ilya V. Karpov (a1), David Kencke (a2), Derchang Kau (a3), Stephen Tang (a4) and Gianpalo Spadini (a5)...

We present a novel scalable and stackable nonvolatile solid state memory. Each cell consists of a storage element, based on phase change memory (PCM) element, and an integrated selector, using an Ovonic threshold switch (OTS). The cell is implemented to enable a true cross-point array. The main device characteristics and behaviors, corresponding physical processes in different operation modes, and key material properties are discussed.
