A display device and method for fabricating a liquid crystal cell are disclosed. A substantially non-bias plasma treatment is performed in a gas atmosphere containing an inert gas as a main component on the top surface of a metal silicide film of nickel silicide or the like over sourcedrain of a field-effect transistor forming an integrated circuit. The system and method operates to receive in sequence, a plurality of text-based characters. If the wireless communication device can receive the wireless communication service over either one of the frequency band classes, then the system selects one of the frequency band classes based on the first and second communication loads. The backup memory re-programs the first bit data to the flash memory upon detecting a program failure associated with the storing the second bit data.
