Abstract:
A semiconductor device which may be used as an ID chip and data may be rewritten only one time. In addition, a semiconductor device may be used as an ID chip and data may be written except when manufacturing the chip. The invention has a modulating circuit, a demodulating circuit, a logic circuit, a memory circuit, and an antenna circuit over an insulating substrate. The modulating circuit and the demodulating circuit are electrically connected to an antenna circuit, the demodulating circuit is connected to the logic circuit, the memory circuit stores an output signal of the logic circuit, and the memory circuit is a fuse memory circuit using a fuse element.
