Volatile memory or volatile storage is computer memory that requires power to maintain the stored information. It retains its contents while powered, but when power is interrupted stored data is immediately lost. Non-volatile memory is memory that maintains its content even when unpowered.
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, and is vulnerable to malicious access only while powered.
