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.
Originally designed to operate with Intel's NOR-based execute in place (XIP) flash memory, CompactFlash memory cards were converted over to NAND format and have since become the preferred memory card for professional videographers using digital video cameras.
