摘要： An electronic data flash card includes a processor and at least one flash memory device. The flash memory is partitioned such that it includes a first partition that is formatted using a file system that supports an Autorun function (e.g., CD-ROM file system (CDFS) format, fixed-disk format or Universal Disk Format (UDF)), and a disk partition that is formatted using a typical controller-based flash device file system (e.g., 16-bit File Allocation Table (FAT16) file system, 32-bit FAT (FAT32) file system, or New Technology File System (NTFS)). The electronic data flash card is produced such that Autorun-enabled application automatically executes a predetermined application or action when the electronic data flash card is installed in a host system. In one embodiment, the Autorun application includes an advertisement displayed on the host system prior to allowing access to data stored in the disk partition.

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 is accessible by a host system, and includes a flash memory controller and at least one flash memory device coupled to the flash controller. The boot code and control code for the flash memory system (flash card) are stored in the flash memory device during a programming procedure. The flash controller transfers the boot code and control code to a volatile main memory (e.g., random access memory or RAM) at start up or reset making a RAM-based memory system. Boot code and control code are selectively overwritten during a code updating operation. A single flash controller thus supports multiple brands and types of flash memory to eliminate stocking issues.
摘要翻译：电子数据闪存卡可由主机系统访问，并且包括闪存控制器和耦合到闪存控制器的至少一个闪存设备。闪存系统（闪存卡）的启动代码和控制代码在编程过程中存储在闪存设备中。闪存控制器在启动或复位时将引导代码和控制代码传送到易失性主存储器（例如，随机存取存储器或RAM），从而形成基于RAM的存储器系统。引导代码和控制代码在代码更新操作期间被有选择地覆盖。因此，单个闪存控制器支持多种品牌和类型的闪存，以消除存货问题。

摘要： A flash system has multiple channels of flash memory chips that can be accessed in parallel. Host data is assigned to one of the channels by a multi-channel controller processor and accumulated in a multi-channel page buffer. When a page boundary in the page buffer is reached, the page buffer is written to a target physical block if full, or combined with old data fragments in an Aggregating Flash Block (AFB) when the logical-sector addresses (LSA's) match. Thus small fragments are aggregated using the AFB, reducing erases and wear of flash blocks. The page buffer is copied to the AFB when a STOP command occurs. Each channel has one or more AFB's, which are tracked by an AFB tracking table.

摘要： An extended universal-serial bus (EUSB) bridge to a host computer can have peripheral component interconnect express (PCIE) protocol layers on one side of the bridge, and EUSB layers on the other side of the bridge, with a high-level bridging converter module connecting the upper layers. The PCIE physical, data-link, and transport layers may be eliminated by integrating the bridge with an I/O controller. PCIE requests and data payloads are directly sent to the bridge, rather than low-level PCIE physical signals. The PCIE data payloads are converted to EUSB data payloads by a high-level direct bridging converter module. Then the EUSB data payloads are passed down to an EUSB transaction layer, an EUSB data-link layer, and an EUSB physical layer which drives and senses physical electrical signals on both differential pairs of the EUSB bus.

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 flash microcontroller has a Static Random-Access-Memory (SRAM) buffer that stores several blocks of boot code read from a flash memory. The SRAM buffer also operates as a cache of flash data after booting is complete. Cache read and write hits use the SRAM cache rather than flash memory, while old cache lines and read misses access the flash memory. Both the external host and the microcontroller are booted from boot code buffered in the SRAM buffer. A boot-loader state machine reads the flash ID and programs flash parameter registers with timing parameters for the flash memory. The flash microcontroller uses a differential interface to the external host, with a differential transceiver and a differential serial interface. Frame, packet, and encoded clock processing is also performed by the serial interface.
