Historically, the application of phase-change materials and devices has been limited to the provision of non-volatile memories. Recently, however, the potential has been demonstrated for using phase-change devices as the basis for new forms of brain-like computing, by exploiting their multilevel resistance capability to provide electronic mimics of biological synapses. In this talk a different and previously under-explored property that is also intrinsic to phase-change materials and devices, namely accumulation, will be presented to demonstrate that nanometer-scale electronic phase-change devices can also provide a powerful form of arithmetic computing leading potentially to a new type of phase-change based arithmetic logic unit (ALU) for general purpose computing.
