Volatile memory, contrary to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted the stored data is immediately lost.

Volatile memory has several uses, for example as a RAM drive. In addition to usually being faster than forms of mass storage such as a hard drive, volatility can protect sensitive information, which becomes unavailable on power-down.
