A passive adapter for portable memory cards has a bridge unit, which is inserted in a corresponding PCMCIA card interface. The bridge unit employs a first controller to detect the PCMCIA card interface, which is made in form of a module comprising a slot and a second controller. The slot allows different memory cards to plug on one-at-a-time basis for the controller to detect the category of an inserted memory card. This invention is characterized in: removing the second controller of the module and adding the functions of the second controller to the first controller of the bridge unit and using an added detection-signal conversion controller of the module for detection of the memory cards.
