A flash memory device is disclosed and includes; a memory cell array, a high voltage generating circuit generating a high voltage applied to a selected word line to select one or more memory cells in the memory cell array, and a controller. A protective film having superior gas barrier properties is previously formed on a heat-resistant substrate other than a substrate with the element formed thereon. Furthermore, a novel inputoutput device that is highly convenient or reliable is provided. A spring of the assembly is positioned around a threaded end portion of the bolt in order to maintain the bolt recessed within the aperture of the outer cap as the outer cap and bumper block are moved between expanded and compressed positions. Other embodiments include a system and device configured to perform the method. The cargo box has a floor that is located between the steering column and the at least one riding wheel.
