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.
