发明名称 PASSIVE CONTACTLESS INTEGRATED CIRCUIT COMPRISING A FLAG FOR MONITORING AN ERASE/PROGRAMMING VOLTAGE
摘要 A passive contactless integrated circuit includes an electrically programmable non-volatile data memory (MEM), a charge accumulation booster circuit for supplying a high voltage necessary for writing data in the memory. The integrated circuit includes a volatile memory point for memorizing an indicator flag, and circuitry for modifying the value of the indicator flag when the high voltage reaches a critical threshold for the first time after activating the booster circuit.
