Abstract: A multi-slave interface card reader includes a card reader body having a USB signal interface plug and a 3C memory card interface receptacle installed on one side of the body being vertical to the USB signal interface plug for placing a memory card, e.g. Mini-SD, RS-MMC, Micro-SD, or Micro-MMC. Since the card reader body has the memory card installed therein, it is possible to place the card reader body in devices like cameras, MP3's, mobile phones . . . and so forth, to act as a memory. The USB signal interface plug can be directly connected to a computer host, or the card reader body can be connected to another card reader for transferring the data stored in the memory card to the computer through the card reader. Such a device of single body with multiple interfaces allows users to employ across various platforms, meanwhile also provides cost down benefits for manufacturers.

Abstract: A memory packaging structure of mini SD card, the main implementation technology thereof comprises: to perform the pin adjustment to the: memory originally employing TSOP (Thin Small Out-Line Package) packaging structure, eliminating the gap of 0.1 mm to 0.2 mm between the memory and the circuit board, thus completely attached to the circuit board; to leave the top end of the mini SD card open to directly expose the top end of the memory on the surface of the mini SD card, reducing the thickness of a layer of coverage; to cover the pins on the both sides of the memory to hind them, wherein applying glue joint between the auxiliary lateral body and memory pins to enhance the attachment.

Abstract: A memory card module includes a first circuit board, and a second circuit board. On one surface of the first circuit board, there are flash memories and a controller. The second circuit board is installed at one end of the first circuit board and is electrically connected with the first circuit board so as to form a transmitting interface port. On a first surface of the second circuit board, there are a plurality of interface connecting points. On a second surface of the second circuit board, part of the second surface is hollowed out. A space formed between the hollowed out area and the corresponding first circuit board increases the area for circuit layouts and the mounting components for the first circuit board. Therefore, quantity of accommodated memory components may be increased so as to increase the total storage capacity of the memory card under limitation of small dimensions.

Abstract: A memory card with test contacts having protection on an interface is provided. The claimed memory card comprises a card body having a circuit board therein, a control chip on the circuit board used to control data reading and writing of the memory card, a memory chip on the circuit board used to store data for the memory card, a memory card interface electrically connecting to the control chip, a connection interface, electrically connecting control chip, and a lid or a tab on the memory card interface or on the connection interface to protect test contacts on the interfaces.

Abstract: An application IC that can be applied in the control system of a memory storage device for the USB device for communicating with a server for receiving, reading and writing commands from the server and to access to the data stored in various memory storage devices is provided. Alternatively, the application IC can support the server, including IDE portable information product for data transmission. The data transmission having these two different specifications can share the same data source in certain mechanism. In this mechanism, the USB server is in the first priority transfer mode, the IDE server will take action only when the USB server is unavailable or discharged. When the IDE server is in operation mode, the interruption demand from the USB server is denied and after the IDE server completes the assignment, the interruption command from the USB server is executed.

Abstract: A wireless sound apparatus capable of picking up the MP3 formatted file transmitted by a wireless information product and then the MP3 formatted file is encoded/decoded by the MP3 encoder/decoder/recorder IC unit into an analog signal that can be output by the speaker or MP3 formatted data can be recorded for storing into the wireless sound apparatus. Thus there is no need for the user to carry MP3 player or portable ROM/PDA for listening to music. Thus, by using the wireless sound apparatus of the present invention, the user is able to enjoy the music without any limitation.
