Flash memory device having flame resistant

The invention provides a flash memory device having flame resistant, which comprises a first shell, a first circuit board, and a first transmission interface. The first circuit board will be disposed within the first shell, is covered by fire protection materials, and comprises a controller and a plurality of flash memory elements. The first transmission interface is disposed outside the first shell. An electrical connection line is connected between the first circuit board and the first transmission interface. By the flash memory elements being accommodated within the fire resistant shell, the fire resistant shell will be for isolating high temperature to avoid the flash memory elements being burnt when the flash memory device exists in a fire scene.
