摘要： A method of initializing a non-volatile memory system is disclosed. System data are written to a non-volatile memory based on a formula rule at a factory, and a number of copies of the system data are written to the non-volatile memory. The system data are searched in the non-volatile memory according to the formula rule and a selected data access mode. At least one operating parameter of the selected data access mode is reconfigured, followed by checking if the searched system data are successfully read. The system data are utilized to set the at least one operating parameter of the non-volatile memory system when the searched system data are successfully read from the non-volatile memory.

摘要： A management platform for extending lifespan of memory, such as SD, MMC, micro SD, of storage devices is provided. The memory includes a plurality of virtual access units, and a virtual block is defined to include a fixed number of virtual access units. In the management platform, a memory control unit tallies the number of operations performed on a virtual access unit when the virtual access unit is selected to perform on. A processing unit determines whether the data stored in virtual access units should be move to another virtual access unit according to an operation threshold in order to prevent from data loss caused by the memory damage.

摘要： A method for protecting memory proprietary command is provided. By using the logic block area (LBA) address in the header of the LBA mode, the device end can determine whether the data sector in the LBA mode includes a proprietary command. Also, by using the pre-defined computation function to establish a relation among the values stored in a plurality of characteristic point addresses and a specific point address so that he device end can determine whether a proprietary command is received. As the operating system will not filter out the proprietary command wrapped in this manner, the proprietary command can pass the operating system and be executed by the device end.

摘要： The NAND flash memory device contains a NAND flash memory, a mirror data area, and a controller. The mirror data area has a size at least to hold a page of data and is usually formed by random access memory. The controller saves a data to be written into the NAND flash memory that occupies a partial number of the sectors of a first page of the NAND flash memory into the sectors of a second page of the mirror data area. When a new data is to be written into the remaining sectors of the first page of the NAND flash memory, the new data is stored instead into the second page's remaining sectors of the mirror data area. When the second page of the mirror data area is full, the entire second page is written into the first page of the NAND flash memory.

A buffer status array is assigned for the slave unit in a buffer, and either a range status array or a queue status array is assigned for the master unit in the buffer for performing operations of the buffer controller in an accessing-by-block manner or in an accessing-by-spaced-interval manner. The master unit cooperated with the slave unit is determined from the at least one master unit by using a starvation-preventing algorithm.

摘要： A control mechanism for multi-functional chips is provided. By receiving operation signals from the predefined pins of the different operation functions, the present invention accesses the corresponding storage area in the memory module according to the operation signals without using different memory modules and memory controllers corresponding to different operation functions so as to save power and reduce the hardware size. For example, the MegaSIM™ multi-functional chip includes the integration of a plurality of operation functions, such as SD/MMC and ISO 7816. Each operation function uses different communication protocol to provide operation signals through individual to shared predefined pins. For example, MegaSIM™ I/O, Vpp/CLK, GND, CLK RST, and Vcc pins are used by ISO 7816, and Cmd, Data0, and Vpp/CLK pins are used by SD/MMC.

摘要： A card reader with capability of adjusting the access interface display is provided, including a connection interface for electrically connecting to the host, a plurality of access interfaces for electrically connecting to corresponding memory cards, such as SD, CF, and a controller. When the host completes the enumeration, the controller issues a disconnect signal through the connection interface to the host to erase the original disk mappings, such as G:, F:, on the display for subsequent adjustment. For adjusting the display, the controller issues an optional reconnect signal belonging to the card reader to the host so that the host can execute the re-enumeration and adjust the displaying of the access interface available in the card reader according to the optional reconnect signal.
