摘要： A Multi-Media Card (MMC) Single-Chip Flash Device (SCFD) contains a MMC flash microcontroller and flash mass storage blocks containing flash memory arrays that are block-addressable rather than randomly-addressable. An initial boot loader is read from the first page of flash by a state machine and written to a small RAM. A central processing unit (CPU) in the microcontroller reads instructions from the small RAM, executing the initial boot loader, which reads more pages from flash. These pages are buffered by the small RAM and written to a larger DRAM. Once an extended boot sequence is written to DRAM, the CPU toggles a RAM_BASE bit to cause instruction fetching from DRAM. Then the extended boot sequence is executed from DRAM, copying an OS image from flash to DRAM. Boot code and control code are selectively overwritten during a code updating operation to eliminate stocking issues.

摘要： A Low-power flash-memory device uses a modified Universal-Serial-Bus (USB) 3.0 Protocol to reduce power consumption. The bit clock is slowed to reduce power and the need for pre-emphasis when USB cable lengths are short in applications. Data efficiency is improved by eliminating the 8/10-bit encoder and instead encoding sync and framing bytes as 9-bit symbols. Data bytes are expanded by bit stuffing only when a series of six ones occurs in the data. Header and payload data is transmitted as nearly 8-bits per data byte while framing is 9-bits per symbol, much less than the standard 10 bits per byte. Low-power link layers, physical layers, and scaled-down protocol layers are used. A card reader converter hub allows USB hosts to access low-power USB devices. Only one flash device is accessed, reducing power compared with standard USB broadcasting to multiple devices.

摘要翻译： 低功耗闪存设备使用修改后的通用串行总线（USB）3.0协议来降低功耗。 当应用程序中的USB电缆长度短时，位时钟减慢了功率，并且需要预加重。 通过消除8/10位编码器并将同步和成帧字节编码为9位符号来提高数据效率。 数据字节只有在数据中出现一系列6个数据字节时才能通过位填充进行扩展。 标头和有效载荷数据以每个数据字节近8位的形式传输，而成帧是每个符号9位，远远小于每个字节的标准10位。 使用低功率链路层，物理层和缩小协议层。 读卡器转换器集线器允许USB主机访问低功耗USB设备。 只有一个闪存设备被访问，与标准的USB广播相比，将功耗降低到多个设备。

摘要： A flash drive has increased endurance and longevity by reducing writes to flash. An Endurance Translation Layer (ETL) is created in a DRAM buffer and provides temporary storage to reduce flash wear. A Smart Storage Switch (SSS) controller assigns data-type bits when categorizing host accesses as paging files used by memory management, temporary files, File Allocation Table (FAT) and File Descriptor Block (FDB) entries, and user data files, using address ranges and file extensions read from FAT. Paging files and temporary files are never written to flash. Partial-page data is packed and sector mapped by sub-sector mapping tables that are pointed to by a unified mapping table that stores the data-type bits and pointers to data or tables in DRAM. Partial sectors are packed together to reduce DRAM usage and flash wear. A spare/swap area in DRAM reduces flash wear. Reference voltages are adjusted when error correction fails.

摘要： A smart flash drive has one or more levels of smart storage switches and a lower level of single-chip flash devices (SCFD's). A SCFD contains flash memory and controllers that perform low-level bad-block mapping and wear-leveling and logical-to-physical block mapping. The SCFD report their capacity, arrangement, and maximum wear-level count (WLC) and bad block number (BBN) to the upstream smart storage switch, which stores this information in a structure register. The smart storage switch selects the SCFD with the maximum BBN as the target and the SCFD with the lowest maximum WLC as the source of a swap for wear leveling when a WLC exceeds a threshold that rises over time. A top-level smart storage switch receives consolidated capacity, arrangement, WLC, and BBN information from lower-level smart storage switch. Data is striped and optionally scrambled by Redundant Array of Individual Disks (RAID) controllers in all levels of smart storage switches.
