摘要：
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.
