IBM, Infineon and Macronix announced today a joint research initiative to explore the potential of a new form of computer memory technology called phase-change memory (PCM).
PCM is a novel technology that stores data by changing the state of a special material from an amorphous to a crystalline structure, rather than storing data as an electrical charge. While in its early stages, the technology shows potential for high speed, high density storage of data, while retaining data even when power is turned off. Such attributes could be beneficial in applications ranging from high performance servers to consumer electronics.
