ABSTRACT:
An IC card for outputting attribute information includes ROMs, a connector interfacing with an external unit, transmitting/receiving circuitry for exchanging control signals, address signals, and data, data output buffer for the ROMs mode control circuit for controlling the active or inactive state of each of the storage and data output buffer, and attribute information setting circuit containing the attribute information of the IC card. This card structure results in a reduced number of components, a simplified circuit configuration, and improved reliability.
