Abstract: The present invention provides a modular packing integrated circuit card and its manufacturing method. The above modular packing integrated circuit card comprises a shell, a composite chip unit, and a switch card with a specific interface format. The switch card has a predetermined space for locating the composite chip unit, and enabling the predetermined pins of the composite chip unit to be connected with the predetermined lines of the switch card. The switch card further includes an interface device for a specific interface format so as to connect with the predetermined lines. Finally, the switch card is fastened in the shell. Consequently, the composite chip unit can be manufactured as different interface formats by using different switch cards, such that different interface formats are easier to be exchanged with each other.

Abstract: A removable electrical interface device for transferring data to and from a host adapted to operate in one of a universal serial bus (USB) compatible mode, a Mu mode and a non-USB compatible mode includes a first row of contact pads capable of supporting at least one of USB Standard-A connection, Mu mode connection or non-USB compatible mode connection, and a second row of contact pads capable of supporting the Mu mode connection and the non-USB compatible mode connection.

Abstract: A multi-functional electronic card with a multi-I/O interface has a plurality of interface ports for connecting to a host, at least one functional device, and a multi-interface and multi-functional controller. When an interface prot is inserted into the host, other interface ports are off-line automatically. The multi-interface and multi-functional controller is connected to a multi-I/O interface and the functional devices for selecting one functional device. Signals of the multi-I/O interface are converted into signals of the selected functional device so that the host can access the selected functional device.

Abstract: A multi-functional electronic card capable of detecting removable cards includes at least one functional device, a controller, a host interface, and a removable card interface. The host interface has a card detecting pin fixed at a level representing that a card is inserted. The removable card interface has an elastic switch connected to the device detecting pin of the controller. The controller detects event and status of a card insertion and removal by a level change of the device detecting pin for setting the event and status in a status register, and informs the host device through the host interface so that the host device reads the status register to determine whether the removable card is inserted or removed.

Abstract: A mini-type connector has a substrate, a plurality of metal joints and a metal frame. The substrate includes a connector and a circuit board, wherein the connector is extended from the circuit board. The plurality of metal joints is assembled to the connector of the substrate for being electrically connected to an external electronic device. The metal frame covers the connector of the substrate for enhancing the stress-resistance strength of the connector. The connector is integrally formed with the circuit board.

Abstract: A multi-function electronic card has a host interface, a multi-functional controller and a plurality of function devices. Each function device is connected to the host via the host interface by issuing an interrupt request to the multi-functional controller. The multi-functional controller has an interrupt queue and an interrupt status register, each bit of the interrupt status register corresponding to a function device. When a function device issues an interrupt request, an identification number of the function device is stored into the interrupt queue, and only when all the bits in the interrupt status register are zeros, a corresponding bit in the interrupt status register is set as 1 for issuing an interrupt request to the host. When the host has serviced the function device, the interrupt queue is updated and the interrupt status register is cleared.

Abstract: An electronic card with dynamic memory allocation management is provided, which requires only one single memory by utilizing a dynamic memory controller having a selector and a first, a second and a third base registers. A first DMA controller provides an output address added to the first base register for performing data access. A micro-controller provides an output address added to the second base register for performing data access. A second DMA controller provides an output address added to the third base register for performing data access. When the micro-controller, the first DMA controller or the second DMA controller issues an access request to the memory, the dynamic memory controller selects one of the micro-controller, and the first and second DMA controllers to access the memory based on a sequence of the access requests.

Abstract: A non-volatile memory based storage system capable of directly overwriting without using redundancy and its writing method are provided. The invention first writes data into a register. Then, a portion of MCF information of the decoded logical writing destination address is taken as a physical writing address and used to determine whether there is data in a block corresponding to the physical writing address. If yes, a new swap block is taken out from a swap table and at least one record of data in the register is written into the swap block.
