    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: 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 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.

    摘要: Through the use of an allocation logic unit with a Flash controller, a single primary chip enable is de-multiplexed into a multiple secondary chip enables for multiple Flash memory dies or chips. In so doing, Flash storage device capacity is greatly expanded. In a first aspect, a memory package includes a plurality of memories; and an allocation logic unit coupled to the plurality of memories for receiving a single chip enable signal. The allocation logic unit de-multiplexes the single chip enable signal to a plurality of chip enable signals. Each of the plurality of chip enable signals access to one of the plurality of memories.In a second aspect, a printed circuit board (PCB) includes a Flash controller for providing at least one primary chip enable signal. 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 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.
