Abstract: The present invention relates to a common connector for memory cards and a switching arbitration method for the shared Pins of the connector, i.e., a common connector which allows many different types of memory cards to be inserted in and fixed at different times. A multiple of rows/sets of different types of Pins are devised on one side of a baseboard of the common connector. And particularly, a set of shared Pins enables identification of interface signals from SD/MMC cards or SM cards. Under the control of corresponding memory card detection switches and switching arbitration circuits, the shared Pins can be connected to interface signals from a SD/MMC card or a SM card. Therefore, such a structure not only reduces the size of the common connector but also supports a multiple of types of memory cards.
