摘要: The invention relates to exchangeable memory or PC-cards with several integrated circuits for personal computers. These are used as a large capacity mass replacing floppy disks and other magnetic supports. To protect the content of these against unauthorized use, proposes incorporation into card (CC) specific security circuit chip (MPS), which performs clearance function access chips (MEM). A microcontroller (MPC) also placed in comnunicates computer circuit. It makes validate confidential code introduced from computer, whilst supplying control signals validation result.
