Abstract
In order to eliminate limitation upon the frequency of a carrier wave from externally, this IC chip for identification includes: a power supply section which receives this carrier wave from outside and creates an internal power supply; a clock signal generation section for read out which generates an internal clock signal for read out based upon a clock signal pulse which is superimposed upon an optical signal from externally; a memory section; and an output section which serially reads out data in the memory section according to the internal clock signal for read out, and load modulates the carrier wave from outside based thereupon.
