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.
There are typically five parts to a flash drive: 1  Standard-A USB plug â provides a physical interface to the host computer. 2  USB mass storage controller â a small microcontroller with a small amount of on-chip ROM and RAM. 3  NAND flash memory chip(s) â stores data (NAND flash is typically also used in digital cameras).
