Volatile_memory

Volatile memory, also known as volatile storage or primary storage device, is computer memory that requires power to maintain the stored information, unlike non-volatile memory which does not require a maintained power supply.

Most forms of modern random access memory are volatile storage, including dynamic random access memory and static random access memory. Content addressable memory and dual-ported RAM are usually implemented using volatile storage. Early volatile storage technologies include delay line memory and Williams tube.
