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： A case-grounded flash-memory drive has a printed-circuit board assembly (PCBA) with flash-memory chips and a controller chip. The PCBA is encased inside an upper case and a lower case, with a Serial AT-Attachment (SATA) connector that fits through and opening between the cases. The cases can be assembled with the PCBA by a snap-together, ultrasonic-press, screw-fastener, or thermal-bond adhesive method. Dual-axis case-grounding pins draw any electro-static-discharges (ESD) current off the upper case along a primary axis and onto a PCBA ground through a secondary axis washer that is screwed into the PCBA. The primary axis body of the dual-axis case-grounding pins fits around a PCBA notch while the secondary axis passes through a metalized alignment hole for grounding. When the SATA connector is inserted into a host, the host ground sinks ESD currents collected by the dual-axis case-grounding pins.

摘要： A Universal-Serial-Bus (USB) device has a USB plug with reduced wobble. A USB metal wrap around the perimeter of the USB plug is attached to a housing by overmolding. A plug supporter is inserted into the front of the USB metal wrap, and has locking tabs that snap over the inside wall of the housing. Side tabs on the plug supporter fit into side slots on the USB metal wrap to secure the plug supporter inside the USB metal wrap. A circuit board with a USB flash controller has USB metal contacts on an extension end that is inserted through the housing and into the USB metal wrap. The extension end fits underneath top tabs on the plug supporter, preventing the extension end with the USB metal contacts from upward wobble when the USB plug is inserted into a USB socket.

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.
摘要翻译：电子数据闪存卡包括随机数生成器，其生成存储在卡中的随机数，以及每次主机系统访问卡时的主机系统。主机系统使用随机数来加密逻辑分支地址，用户密码和写入并存储在卡的安全区域中的用户数据。使用与该卡相关联的密钥对该随机数进行加密，并且加密随机数由卡与相关联的加密数据一起存储。随机数不存储在主机系统中。每次查询卡片时都会产生一个新的随机数字。在读取过程中，主机系统使用密钥解密加密的随机数，然后使用随机数来解密相关联的加密数据。对读/写进程的访问受密码保护。

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).

摘要： A flash-memory drive replaces a hard-disk drive using an integrated device electronics (IDE) interface. The flash drive has a printed-circuit board assembly (PCBA) with a circuit board with flash-memory chips and a controller chip. The controller chip includes an input/output interface circuit to an external computer over the IDE interface, and a processing unit to read blocks of data from the flash-memory chips. The PCBA is encased inside an upper case and a lower case, with an IDE connector that fits through and opening between the cases. The cases can be assembled with the PCBA by a snap-together, ultrasonic-press, screw-fastener, or thermal-bond adhesive method. Center lines formed on the inside of the cases fit between rows of flash-memory chips to improve case rigidity. The connector has two rows of pins that straddle the center line of the circuit board for a balanced design.
