摘要： A Universal-Serial-Bus (USB) single-chip flash device contains a USB flash microcontroller and flash mass storage blocks containing flash memory arrays that are block-addressable rather than randomly-addressable. USB packets from a host USB bus are read by a serial engine on the USB flash microcontroller. Various routines that execute on a CPU in the USB flash microcontroller are activated in response to commands in the USB packets. A flash-memory controller in the USB flash microcontroller transfers data from the serial engine to the flash mass storage blocks for storage. Rather than boot from an internal ROM coupled to the CPU, a boot loader is transferred by DMA from the first page of the flash mass storage block to an internal RAM. The flash memory is automatically read from the first page at power-on. The CPU then executes the boot loader from the internal RAM to load the control program.

摘要： A PCI Express-compatible flash device can include one or more flash memory modules, a controller, and an ExpressCard interface. The controller can advantageously provide PCI Express functionality as well as flash memory operations, e.g. writing, reading, or erasing, using the ExpressCard interface. A PIO interface includes sending first and second memory request packets to the flash device. The first memory request packet includes a command word setting that prepares the flash device for the desired operation. The second memory request packet triggers the operation and includes a data payload, if needed. A DMA interface includes sending the second memory request from the flash device to the host, thereby triggering the host to release the system bus for the DMA operation.

The PCB also includes a plurality of Flash memory chips and at least one allocation logic unit coupled to at least a portion of the plurality of Flash memory chips and the Flash controller. The allocation logic unit receives the at least one chip enable signal and de-multiplexes the at least one chip enable signal to a plurality of secondary chip enable signals. Each of the plurality of chip enable signals controls access to one of the Flash memory chips.

摘要： A flash memory card includes a differential datapath that enables communications between the flash memory card and a host device to be performed using differential signals. The differential datapath can translate between the differential signals and card-specific signals that control read/write operations to the memory array of the flash memory card. The card-specific signals can be standard MultiMediaCard, Secure-Digital card, Memory Stick, or CompactFlash card signals, among others. A host device that provides differential data transfer capability can include a similar differential datapath. By using differential data transfer rather than conventional clocked data transfer, overall data bandwidth between a flash memory card and a host device can be significantly increased, while simultaneously decreasing power consumption and pin requirements.

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 extended Secure-Digital (SD) card has a second interface that uses some of the SD-interface lines. The SD card's mechanical and electrical card-interface is used, but 2 or 4 signals in the SD interface are multiplexed for use by the second interface. The second interface can have a single differential pair of serial-data lines to perform Universal-Serial-Bus (USB) transfers, or two pairs of differential data lines for Serial-Advanced-Technology-Attachment (SATA), Peripheral Component Interconnect Express (PCIE), or IEEE 1394 transfers. 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, and extended SD hosts can read legacy SD cards using just the SD interface, or extended SD cards using the second interface. MultiMediaCard and Memory Stick are alternatives.
