Abstract
A memory card with multiple interface functions is provided. The memory card comprises a multiple interface controller, comprising at least a USB processor, MMC/HS MMC processor and SD processor, and each processor individually connected to a data r/w controller and a shared interface bus, the data r/w controller connected to at least a data-storage medium, and shared interface bus connected to a computer system or IA product. The function of a mode detector/switch is used for detecting the compatible transmitting mode of the connected computer system or IA products, and to switch shared interface bus to match USB processor, MMC/HS MMC processor or SD processor for application. Thus, selecting transmitting mode between data r/w controller and the computer system or IA products connected thereto, the present invention does not only economize on the usage of card reader but also could be applied to various transmitting interface devices and enhancing on its user-friendly performance.
