Abstract: A device for processing and storing data, in particular a chip card, includes a first interface with contacts and a second contactless interface for receiving energy or power from and for communication with a terminal device. A first controllable switching device connects either the first or the second interface to a non-volatile semiconductor memory through address, data and control lines. A logic circuit drives the first controllable switching device. A second controllable switching device disposed between the first controllable switching device and the memory can be driven at least by the logic circuit and an address signal present on the address lines.

Abstract: A chip card includes a semiconductor chip that contains at least one memory. In order to supply energy to the chip and to provide for bi-directional data transmission from and to the chip, both contacts and a device for contactless data transmission are provided. A triggerable switch device which is provided on the chip connects the memory either to the contacts or to the device for contactless data transmission as a function of a state of an output signal of a logic circuit connected to at least a voltage supply contact. The switch device assumes a position of repose when it is not triggered and in that position it connects the memory to the device for contactless data transmission, while only upon application of a voltage to the supply voltage contact, triggered by the logic circuit, does it connect the contacts to the memory.
