Abstract: A multi-format card read/write optical disc drive comprises a micro-controller for processing actions between each component. The micro-controller is connected to a read/write drive, a multi-format card read/write controller, a data codec (coder/decoder), an analog interface transducer, and a computer interface controller. Through the read/write drive and the multi-format card read/write controller, read/write actions are performed to an optical disc and memory cards of various formats, respectively. The data codec is used to decode compressed media data and encode raw data for compression. The analog interface transducer-receives a digital data decoded by the data codec and then converts them into an analog signal for output. The computer interface controller is used to provide connection with a computer for performing bi-directional communications with the computer.

Abstract: The present invention relates to a detection method used in a memory card adaptor and, more particularly, to a detection method used in an adaptor capable of inserting various kinds of memory cards. The present invention comprises mainly the steps of: a control device on an adaptor issuing an identification command to detect a memory card responsive to the identification command, and the control device issuing again a reset command to detect a reset-type memory card if there is no corresponding response; the control device continually awaiting a response signal if there is still no corresponding response; the control device entering a read/write mode corresponding to the memory card if a corresponding response is obtained after issuing the command; and the control device awaiting a read/write command of said master device. The present invention can effectively enhance detection and identification efficiency without the need of adding a hardware switching device.

Abstract: A mouse device capable of storing data comprises a storage medium processor used to control and process actions between each component. The storage medium processor is connected with a device function processor, a mouse function controller, and an interface controller. The storage medium processor has a data read control circuit therein to control access of data in a storage medium. The mouse function controller is used to control and process actions of mouse. The interface controller is used to process signal handshaking and data transmission of a connection interface. A buffer memory management unit connected with a buffer memory is also provided to enhance the speed and stability of data transmission. The mouse device capable of storing device thus has both the storage function of memory peripheral and the cursor control function of mouse.

Abstract: The present invention proposes a control device compatible to Smart Media cards, Memory Stick cards, and NAND-gate type flash memories and applicable to various kinds of capacities and a method for fabricating same. After the control device is turned on and scans physical block addresses of each data block of a memory card one by one, it will partition the memory card into a plurality of segments according to the capacity of a segment lookup table therein. A FAT accessory lookup table in the control device is matched and used for lookup of logical addresses of the FAT. When a host computer is to access a file, the segment lookup table can be used for lookup of data in the segment, and the FAT accessory lookup table will match the operation system to quick find the physical block address when the FAT is accessed. The control device can be compatible to flash memory cards of various kinds of capacities, and the required size of the size of total lookup tables built in RAM can be effectively controlled.
