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： An ExpressCard contains flash memory. The ExpressCard has an ExpressCard connector that plugs into a host, such as a personal computer, digital camera, or personal digital assistant (PDA). A controller chip on the ExpressCard uses a pair of differential Universal-Serial-Bus (USB) data lines in the connector to communicate with the USB host, or can use PCI Express, Firewire, or other protocols. One or more flash-memory chips on the ExpressCard are controlled by a flash-memory controller in the controller chip. Two or more channels of a flash bus have a shared control bus but separate ready lines. The separate ready lines allow flash-memory chips in the two channels to finish operations at different times.

摘要： A flash-drive or flash-card reader connects to a personal computer (PC) through a serial link such as a Universal-Serial-Bus (USB), IEEE 1394, SATA, or IDE. A local CPU acts as the bus master of a CPU bus that connects to slave ports on a flash-memory controller, a serial engine, and a RAM buffer. A second bus in parallel to the CPU bus connects a second slave port on the RAM buffer to a master port on the flash-memory controller and to a master port on the serial engine. The flash-memory controller or the serial engine can use their master ports to transfer data to and from the RAM buffer using the second bus, allowing the CPU to retain control of the CPU bus. The second bus is a flash-serial buffer bus that improves data transfer rates. The flash-memory controller can prefetch into the RAM buffer.

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.
