The present disclosure relates to a silane-containing inorganic nanofiller, a varnish including the silane-containing inorganic nanofiller, an enameled wire including the silane-containing inorganic nanofiller, and a method for preparing the enameled wire. When the program is linked by a linker, only the shared data to which identification information is affixed are extracted and a shared data area is created for the shared data. Then, a lower gate electrode film comprised of a metal nitride film is formed over the gate insulation film. Signals on the data bus are used to drive the multiple peripheral devices.
