    Abstract: A memory card fitted with contacts contains a memory and its access circuits. The memory access circuits are modified to allow recording or reading the memory via electric signals supplied by a terminal according to an asynchronous-type communication protocol with integrity check of the codes transmitted. The signals received on the contacts are analysed by an analysis circuit, then switched to address and data registers by a switch circuit. The analysis circuit and a control circuit transmit messages and codes to the terminal via a transmission circuit.
