Much research into phase change energy storage is centered around refining solutions and using additives and other techniques to engineer around these basic challenges. Often, the specifics of ...

Developed by Stanford Ovshinsky, reknowned for his inventions in memories and solar panels, "phase change RAM" (PRAM, PCRAM) and "chalcogenide RAM" (C-RAM) are other names for phase change memory ...

A rewritable optical disc. First used in drives by Panasonic in the late 1980s, the phase change technology was subsequently employed in all major optical drives, including CD-RW, DVD-RW ...

The concept of phase-change recording is straightforward. An intense laser or current pulse heats and melts the crystalline material, which is subsequently quenched into the amorphous state. To ...
