摘要： An electronic data flash card is accessible by a host computer, and includes a processing unit connected to a flash memory device that stores a data file, and an input-output interface circuit activated so as to establish a communication with the host computer. In an embodiment, the electronic data flash card uses a USB input/output interface circuit for communication with the host computer. A flash memory controller includes an index for converting logical addresses sent by the host computer into physical addresses associated with sectors of the flash memory device. The index is controlled by arbitration logic referencing to values from various look up tables and valid data stored in the flash memory device. The flash memory controller further includes a first-in-first-out unit (FIFO) for recycling obsolete sectors of the flash memory device in the background process so that they are available for reprogramming.

摘要： An extended Secure-Digital (SD) card has a second interface that uses some of the SD-interface lines. A card-detection routine on a host can initially use the SD interface to detect extended capabilities and command the card to switch to using the second interface. The extended SD card can communicate with legacy SD hosts using just the SD interface, or extended SD cards using the second interface. Also an extended Universal-Serial Bus (EUSB) host enters a suspend mode rather than polling an EUSB device that is busy performing a memory or other operations. Power is saved since polling is avoided. The busy EUSB device sends a not-yet signal back to the EUSB host to instruct the host to enter the suspend mode. When the EUSB device is ready to continue transfer with the host, the EUSB device wakes up the host by sending a ready signal back to the host.
摘要翻译：扩展的安全数字（SD）卡具有使用一些SD接口线路的第二接口。主机上的卡检测程序最初可以使用SD接口来检测扩展功能，并命令卡切换到使用第二个接口。扩展SD卡可以使用SD接口与传统SD主机进行通信，也可以使用第二个接口与扩展SD卡进行通信。扩展的通用串行总线（EUSB）主机也进入暂停模式，而不是轮询正忙于执行内存或其他操作的EUSB设备。省电，因为避免轮询。忙碌的EUSB设备向EUSB主机发送一个尚未回复的信号，指示主机进入挂起模式。当EUSB设备准备好继续与主机进行传输时，EUSB设备通过向主机发送就绪信号来唤醒主机。

摘要： An electronic data flash card includes a random number generator that generates a random number stored in the card and a host system each time the card is accessed by the host system. The random number is used by the host system to encrypt a logical branch address, a user password, and user data that is written to and stored in a secure area of the card. The random number is encrypted using a key associated with the card, and the encrypted random number is stored by the card with the associated encrypted data. The random number is not stored in the host system. A new random number is generated each time the card is queried. In a read process the host system decrypts the encrypted random number using the key, then uses the random number to decrypt the associated encrypted data. Access to read/write processes are password protected.

摘要： A high volume testing/formatting process is provided for Universal Serial Bus-based (USB-based) electronic data flash cards (USB devices) that meets the increasing demand for USB electronic data flash cards (USB devices). A test host is simultaneously coupled to the multiple USB devices (e.g., using a multi-port card reader or a probe fixture), a controller endpoint value is read from each of the USB devices and verified with a known good value, and then testing/formatting is performed on each of the USB devices by writing predetermined data into each USB device in a pipelined manner, then reading out and testing the predetermined data. In one embodiment, the test host implements a special a USB driver that blocks standard USB registration procedures upon detecting the plurality of USB devices. Control and/or boot code data are written onto the flash memory device (i.e., instead of being provided on a controller ROM).
