    摘要: A flash-card reader improves transmission efficiency by using bulk streaming of multiple pipes. A bulk data-out pipe carries host write data to the card reader and can operate in parallel with a bulk data-in pipe that carries host read data that was read from a flash card attached to the card reader. Status packets do not block data packets since the he status packets are buffered through a separate status pipe, and commands are buffered through a command pipe. Flash data from multiple flash cards are interleaved as separate endpoints that share the bulk data-in pipe. A data in/out streaming state machine controls streaming bulk data through the bulk data-in and data-out pipes, while a status streaming state machine controls streaming status packets through the status pipe. Transaction overhead is reduced using bulk streaming where packets for several commands are combined into the same bulk streams.

    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: A flash module has raw-NAND flash memory chips accessed over a physical-block address (PBA) bus by a NVM controller. The NVM controller is on the flash module or on a system board for a solid-state disk (SSD). The NVM controller converts logical block addresses (LBA) to physical block addresses (PBA). Data striping and interleaving among multiple channels of the flash modules is controlled at a high level by a smart storage transaction manager, while further interleaving and remapping within a channel may be performed by the NVM controllers. A SDRAM buffer is used by a smart storage switch to cache host data before writing to flash memory. A Q-R pointer table stores quotients and remainders of division of the host address. The remainder points to a location of the host data in the SDRAM. A command queue stores Q, R for host commands.

    摘要: Peripheral devices store data in non-volatile phase-change memory (PCM). PCM cells have alloy resistors with high-resistance amorphous states and low-resistance crystalline states. The peripheral device can be a Serial AT-Attachment (SATA) or integrated device electronics (IDE) PCM solid-state disk or a Multi-Media Card/Secure Digital (MMC/SD) card. A peripheral PCM controller accesses PCM mass storage devices containing PCM memory chips that form a mass-storage device that is block-addressable rather than randomly-addressable. SATA, IDE, or MMC/SD transactions from a host bus are read by a bus transceiver on the peripheral PCM controller. Various routines that execute on a CPU in the peripheral PCM controller are activated in response to commands in the host-bus transactions. A PCM controller in the peripheral controller transfers data from the bus transceiver to the PCM mass storage devices for storage.

    摘要: Methods and systems of managing memory addresses in a large capacity multi-level cell based flash memory device are described. According to one aspect, a flash memory device comprises a processing unit to manage logical-to-physical address correlation using an indexing scheme. The flash memory is partitioned into N sets. Each set includes a plurality of entries (i.e., blocks). N sets of partial logical entry number to physical block number and associated page usage information (hereinafter ‘PLTPPUI’) are stored in the reserved area of the MLC based flash memory. Only one the N sets is loaded to address correlation and page usage memory (ACPUM), which is a limited size random access memory (RAM). In one embodiment, static RAM (SRAM) is implemented for fast access time for the address correlation. LSA received together with the data transfer request dictates which one of the N sets of PLTPPUI is loaded into ACPUM.
