"RAM disk"

By Juergen Haas, About.com

Definition: RAM disk: An area of random-access memory (RAM) configured by a utility program to emulate a hard disk drive. Data stored in a RAM disk can be accessed more quickly than data stored on a disk drive, but this data is erased whenever you turn off or reboot the computer. See configuration file, device driver, and RAMDRIVE.SYS. From QUECID
