A circuit module of a memory card is selectively used with card readers/writers compliant with different access protocols. The circuit module includes a shared non-volatile memory; a first transmission control unit communicable with a first card reader/writer for controlling data transmission from/to the first card reader/writer; a second transmission control unit communicable with a second card reader/writer for controlling data transmission from/to the second card reader/writer; and a data buffer and memory access controller coupled to the non-volatile memory and the first and second transmission control units for conducting a data transmission path between a designated transmission control unit and the non-volatile memory, thereby allowing data transmission between the designated card reader/writer and the non-volatile memory. The circuit module can be grouped with different carrier housings to produce a memory card kit.
