Abstract
A semiconductor integrated circuit apparatus capable of reading out semiconductor information stored therein is provided. A semiconductor information storage section has semiconductor information unique to a semiconductor integrated circuit apparatus stored therein. The unique semiconductor information includes, for example, an identification number for identifying the semiconductor integrated circuit apparatus and information for identifying the time of manufacture such as a lot number. An externally provided storage apparatus has a readout program stored therein for reading the semiconductor information of the semiconductor integrated circuit apparatus as required. When a signal of request for the semiconductor information is supplied from the outside, a semiconductor information output section reads out the semiconductor information from the semiconductor information storage section in response to the signal and writes the read-out semiconductor information into the external storage apparatus in accordance with the readout program in the storage apparatus if the program is executed.
