ABSTRACT:
The invention relates to exchangeable memory or PC-cards having several integrated circuits for personal computers.
These memory or PC-cards serve as a large capacity mass memory for replacing floppy disks and other exchangeable magnetic supports. In order to improve the possibilities of these cards, it is proposed that to them be added a microprocessor (MPC) and the direct wiring of the operational bus (BD2) of said microprocessor to the card memory (MEM). In this way, a card is obtained which contains in direct form performable programs previously loaded by the computer (PC) in which has been inserted the card. Thus, the microprocessor functions not only with an internal set program memory, but also with performable programs loaded into the card by the computer and which can therefore be modified at random (provided that the user clearance procedures are respected).
