Abstract: The invention relates to contact memory cards (16) essentially comprising a memory (10) and its approach circuits (12, 14). The invention is characterized in that the approach circuits of the memory are modified (20) to allow for writing in or reading the memory (10) by means of electrical signals supplied by the terminal (18) in accordance with an asynchronous communication protocol with verification of the integrity of the transmitted codes. The signais received at the contacts (16) are analysed by the circuit (22) and then directed to the address register (26) and data register (28) by the switch circuit (24). The circuit (22) and the control circuit (14) transmit messages and codes to the terminal (18) by way of a transmission circuit (34). L'invention concerne les cartes à mémoire à contacts (16) qui comportent essentiellement une mémoire (10) et ses circuits d'accès (12, 14). L'invention réside dans le fait que les circuits d'accès à la mémoire sont modifiés (20) pour permettre l'enregistrement ou la lecture de la mémoire (10) à l'aide de signaux électriques fournis par le terminal (18) selon un protocole de communication du type asynchrone avec vérification de l'intégrité des codes transmis. Les signaux reçus sur les contacts (16) sont analysés par le circuit (22), puis aiguillés vers les registres d'adresse (26) et de données (28) par le circuit d'aiguillage (24). Le circuit (22) et le circuit de contrôle (14) transmettent des messages et des codes au terminal (18) par un circuit de transmission (34).

Abstract: The card has input and output circuits (12,14) which are modified by a circuit (20) that allows reading and writing of memory by signals from a terminal (18) using an asynchronous communication protocol with verification of code integrity. The signals are analyzed (22) then directed to a register (26) and a data register (28) by a switch circuit (24), and sent via a transmission circuit (34).

Abstract: A load modulation device in a remotely powered integrated circuit includes an oscillating circuit, and a voltage device for regenerating first and second power supply voltages. The voltage device includes at least one MOS transistor in a well on at least one terminal of the oscillating circuit. The at least MOS transistor includes a source or drain connected to the at least one terminal. A bias circuit biases the well to the first or second power supply voltage based upon a modulation signal.
