Beschreibung
Zusammenfassung:A chip includes a memory that stores confidential data, a power supply device to apply a voltage and/or or a current, and an interface to transfer the data from and/or to another device. To secure the data in the memory, the power supply device is an integrated component of the chip. The power supply device is equipped with a limited, non-replenishable fuel reservoir so that data can be maintained in the memory over a limited service life. In other embodiments, voltage provided by the power supply device can also be employed actively to delete data in the memory in the event of unauthorized access to the chip.
