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 dual-mode Universal-Serial-Bus (USB) switch can operate in a normal hub mode to buffer transactions from a host to multiple USB flash storage blocks that are USB endpoints. When operating in a single-endpoint mode, the dual-mode USB switch intercepts packets from the host and responds to the host as a single USB endpoint. The USB switch aggregates all downstream USB flash storage blocks and reports a single pool of memory to the host as a single virtual USB memory. Adjacent transactions can be overlapped by packet re-ordering. A token packet that starts a following transaction is re-ordered to be sent to the USB flash storage blocks before the data and handshake packets that end a first transaction, allowing the second transaction to begin accessing the flash memory earlier. Data can be mirrored or striped across several USB flash storage blocks and parity can be added for error recovery.

摘要： A flash-card exchanger has two modes of operation. When a host personal computer (PC) is connected to a Universal-Serial-Bus (USB) connector, the flash-card exchanger operates in a card reader mode, allowing the host to read data from removable flash-memory cards inserted into connector slots of the flash-card exchanger. When the host PC is not connected, a USB flash-memory thumb or key-chain drive can be inserted into a second USB connector. A USB dual-mode microcontroller acts as a USB host, reading data from the removable flash-memory card and writing the data to the USB-memory key drive using USB packets. Since the USB-memory key drive is small and removable, the user can upgrade to larger storage capacities by plugging in a larger-capacity USB-memory key drive. A flash-exchanger program executing on the USB dual-mode microcontroller copies data from an input-output bus and generates USB packets to the USB-memory key drive.

摘要： A serial flash-memory chip has a serial-bus interface to an external controller. A flash-memory block in the serial flash-memory chip can be read by the external controller sending a read-request packet over the serial bus to the serial flash-memory chip, which reads the flash memory and sends the data back in a data-payload field in a completion packet. Data in a write-request packet is written to the flash memory, and a message packet sent back over the serial bus. The serial bus can be a Peripheral Component Interconnect (PCI) Express bus with bi-directional pairs of differential lines. Packets have modified-PCI-Express headers that define the packet type and data-payload length. Vendor-defined packets can send flash commands such as reset, erase, or responses after operations such as program or erase. A serial engine and microcontroller or state machine are on the serial flash-memory chip.

摘要： An extended Universal-Serial-Bus (USB) connector plug and socket each have a pin substrate with one surface that supports the four metal contact pins for the standard USB interface. An extension of the pin substrate carries another 8 extension metal contact pins that mate when both the connector plug and socket are extended. The extension can be an increased length of the plug's and socket's pin substrate or a reverse side of the substrate. Standard USB connectors do not make contact with the extension metal contacts that are recessed, retracted by a mechanical switch, or on the extension of the socket's pin substrate that a standard USB connector cannot reach. Standard USB sockets do not make contact with the extension metal contacts because the extended connector's extension contacts are recessed, or on the extension of the connector pin substrate that does not fit inside a standard USB socket.
