Abstract
An electronic device includes a semiconductor chip storing an identification number of N-bits and an antenna coupled to the semiconductor chip that sends out the identification number of N-bits. In order to provide a secure and efficient data storage arrangement, the identification number of N-bits is stored in accordance with the presence or absence of through holes that connect wirings to transistors included in the semiconductor chip through an insulating film formed over the transistors.
