Flash memory is a type of nonvolatile memory that erases data in units called blocks. A block stored on a flash memory chip must be erased before data can be written, or programmed, to the microchip. Flash memory retains data for an extended period of time whether a flash-equipped device is powered on or off.
Flash drives are used to store any type of data file, or to move data from one computer to another. USB flash drives have a lot of storage space. It is often easier to use a flash drive than to carry many CD-ROMs. Some computer programs can be run from a USB flash drive.
