    • 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 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).
    • 为通用串行总线(USB)电子数据闪存卡(USB设备)提供了大容量测试/格式化过程,可满足USB电子数据闪存卡(USB设备)日益增长的需求。 测试主机同时耦合到多个USB设备(例如,使用多端口读卡器或探头夹具),从每个USB设备读取控制器端点值,并用已知的良好值进行验证,然后测试 通过以流水线方式将预定数据写入每个USB设备,然后读出并测试预定数据,在每个USB设备上执行/格式化。 在一个实施例中,测试主机在检测到多个USB设备时实现阻止标准USB注册过程的特殊USB驱动器。 控制和/或引导代码数据被写入快闪存储器件(即,不是设置在控制器ROM上)。

    • 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.
    • 电子数据闪存卡可由主机访问,并且包括连接到存储数据文件的闪存设备的处理单元,以及被激活以便与主计算机建立通信的输入 - 输出接口电路。 在一个实施例中,电子数据闪存卡使用USB输入/输出接口电路与主计算机进行通信。 闪速存储器控制器包括用于将由主计算机发送的逻辑地址转换成与闪存器件的扇区相关联的物理地址的索引。 该索引由参考来自各种查找表中的值和存储在闪存设备中的有效数据的仲裁逻辑控制。 闪存控制器还包括先进先出单元(FIFO),用于在后台进程中回收闪速存储器件的过时扇区,使得它们可用于重新编程。

    • A slim male Universal-Serial-Bus (USB) connector fits on only one side of the connector substrate in a standard female USB connector. Wobble or vertical play is reduced by locking depressions in the slim male USB connector that engage metal springs on a metal case that surrounds the female USB connector, locking the two connectors together. Between metal contacts on the slim USM connector are dividers that help fill in gaps when the two connectors are connected together, further reducing play. End rails on the slim USB connector fill in gaps on the sides. The connector substrate of the slim male USB connector can be separate or can be integrated with a circuit board that holds a flash memory chip and a USB controller chip. The connector is wider than the standard width for a better fit. A slim female USB connector for assembly use with the slim male USB connector is also disclosed.
