Examples of non-volatile memory are listed below: Hard disk drive (HDD) Solid state drive (SSD) Flash drive (USB keychain) Optical media (CDs, DVDs, etc) Read-only memory (ROM) Since most storage devices need to maintain data without power, non-volatile memory is far more common than volatile memory. As the volatile solid sublimes, it is deposited on the surface of the cold finger (where it can later be recovered), and is thus separated from the non-volatile substance left in the vessel. (Note that the definitions in some older national regulations and standards may refer to different temperatures.). Join now.
