Abstract

The invention relates to memory cards that can be plugged into personal computers. Personal computers often have a connector designed to receive a memory extension in the form of a plug-in integrated circuit card. The invention proposes a card structure designed for communications between the computer and the exterior (fax, model, etc.), this card being capable of being plugged into the memory extension connector without any need to change the operation protocol of this connector. The card has a connector (CNC) for connection to the computer, a connector (CNX) for connection with the exterior, an internal microprocessor (MP), a non-volatile memory (MNV) containing programs that can be performed by the microcomputer and containing organizational data relating to all the memories of the card, and a volatile memory containing at least one file used for the transfer of the data elements to be exchanged.
