Integrated circuit identification process and corresponding integrated circuits

摘要

The method involves producing an electromagnetic field using an electrically conductive network (REC) realized within an integrated circuit, where the network is passed through electrical transient current or receives transient voltage to generate the electromagnetic field. The characteristics of the voltages are based upon on a value of a digital word forming an identification code for the circuit. The value is stored in a non-volatile memory (NVM) i.e. electrically EPROM (EEPROM), of the circuit, in a secret manner. The field is analyzed whether to discover the code. An independent claim is also included for an integrated circuit comprising a non volatile storage unit.
