Brief history and components of phase change memory.

Sodium Acetate heating pads

Though Phase Change Technology seems to be a new type of technology, it has actually been with us for quite some time. It only recently has been integrated into the data memory industry. Remember those sodium acetate heating pads for sore muscles? How about the heating, venting and air conditioning air ducts we commonly see in industrial buildings? Both utilize some sort of phase change technology, though being used for different applications.

Before we explain how Phase Change Technology applies to the memory data industry, we'll explain the properties/components which comprise "Phase Change Memory" device.

1. In Phase Change Memory, they utilize glass like materials called chalcogenide glass
2. Some common chalcogenide materials are, selenium and tellurium
3. utilizes thermal energy to alter between phases
4. thermal energy conducted through electrodes

now with this brief introduction to "phase change memory" we will further elaborate on this section further down the road.
