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.
Unlike a standard hard drive, the flash drive has no movable parts, containing only an integrated circuit memory chip where data is stored. It usually has plastic casing surrounding the memory chip inside and has a USB connection that is plugged into the USB port on a computer.
