| 摘要 |
The invention concerns an integrated circuit comprising a resonant circuit (L,20) for receiving by electromagnetic induction an alternating voltage (Vac), the resonant circuit comprising at least one capacitance (C1-Ci) switchable by means of a programmed switch (11), the switch comprising a circuit breaker (7), a memory cell (6) and a circuit (31, 32, 33, 42) for controlling the circuit beaker (7), the control circuit being supplied by the alternating voltage (Vac) and arranged for opening or closing the circuit breaker (7) depending on the programming or the erasing status of the memory cell (6).
