"world’s smallest phase-change memory... a thousand times lower than mainstream productspower consumption of a 100-nanometer-sized device created in the lab consumes more than 1000pJ...  Variable memory consumes less than 0.05pJ of power, which is a thousand times less than conventional goods. The phase change memory provides the advantages of good consistency and long life in addition to low power consumption"
