<p>Integrated circuit (106;106') capable of storing data in digital format, particularly for application in a memory card which can be associated for operation with an external acquisition system and an external processing system, comprising: input/output means (2',114',7',122) for receiving the data from the external acquisition system or from the external processing system, for sending the data to the external processing apparatus and for receiving a digital circuit-command signal from the said system and from the said apparatus; a non-volatile electrically programmable memory (101) for storing the said digital data, comprising a first terminal (133) for an electrical programming signal capable of enabling the storage of the data available on the said input/output means and a second terminal (131) for an electrical reading signal capable of enabling the output of the data from the memory to make them available on the input/output means; memory control means (111) connected to the said first and second terminals and to the said input/output means to generate the electrical memory-programming and memory-reading signals from the said command signal. The memory is of the type which can be erased by exposure to electromagnetic radiation, particularly ultraviolet radiation, to permit the non-electrical erasure of the stored data. The integrated circuit can be incorporated in a memory card whose outer casing is provided, at the position of the memory, with means (103) which are transparent to electromagnetic radiation. <IMAGE> <IMAGE></p> |
