摘要： A flash microcontroller has a Static Random-Access-Memory (SRAM) buffer that stores several blocks of boot code read from a flash memory. The SRAM buffer also operates as a cache of flash data after booting is complete. Cache read and write hits use the SRAM cache rather than flash memory, while old cache lines and read misses access the flash memory. Both the external host and the microcontroller are booted from boot code buffered in the SRAM buffer. A boot-loader state machine reads the flash ID and programs flash parameter registers with timing parameters for the flash memory. The flash microcontroller uses a differential interface to the external host, with a differential transceiver and a differential serial interface. Frame, packet, and encoded clock processing is also performed by the serial interface.

摘要： A flash memory system stores blocks of data in Non-Volatile Memory Devices (NVMD) that are addressed by a logical block address (LBA). The LBA is remapped for wear-leveling and bad-block relocation by the NVMD. The NVMD are interleaved in channels that are accessed by a NVMD controller. The NVMD controller has a controller cache that caches blocks stored in NVMD in that channel, while the NVMD also contain high-speed cache. The multiple levels of caching reduce access latency. Power is managed in multiple levels by a power controller in the NVMD controller that sets power policies for power managers inside the NVMD. Multiple NVMD controllers in the flash system may each controller many channels of NVMD. The flash system with NVMD may include a fingerprint reader for security.

摘要： A RAM mapping table is restored from flash memory using plane, block, and page addresses generated by a physical sequential address counter. The RAM mapping table is restored following a plane-interleaved sequence generated by the physical sequential address counter using interleaved bits extracted from the lowest bits of the logical block index. These plane-interleave bits are split into a LSB and a MSB, with middle physical block bits between the LSB and MSB. The physical sequential address counter generates a physical block number by incrementing the plane-interleave bits before the middle physical block bits, and then relocating the MSB to above the middle physical block bits. This causes blocks to be accessed in a low-high sequence of 0, 1, 4096, 4097, 2, 3, 4098, 4099, etc. in the four planes of flash memory. Background recycling and ECC writes are also performed.

摘要： A flash microcontroller has a Static Random-Access-Memory (SRAM) buffer that stores several blocks of boot code read from a flash memory. The boot code includes an initial boot loader, boot code and a control program that are executed by the flash microcontroller, and an operating system OS image and an external-host control program that are executed by an external host. Both the external host and the microcontroller are booted from boot code buffered in the SRAM buffer. A first-reset-read address from the external host is captured by the microcontroller during its boot sequence and stored in a mapping table along with a physical address of the block in the SRAM buffer with the operating system OS image and the external-host control program. A boot-loader state machine reads the flash ID and programs flash parameter registers with timing parameters for the flash memory.

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： An extended universal-serial bus (EUSB) bridge to a host computer can have peripheral component interconnect express (PCIE) protocol layers on one side of the bridge, and EUSB layers on the other side of the bridge, with a high-level bridging converter module connecting the upper layers. The PCIE physical, data-link, and transport layers may be eliminated by integrating the bridge with an I/O controller. PCIE requests and data payloads are directly sent to the bridge, rather than low-level PCIE physical signals. The PCIE data payloads are converted to EUSB data payloads by a high-level direct bridging converter module. Then the EUSB data payloads are passed down to an EUSB transaction layer, an EUSB data-link layer, and an EUSB physical layer which drives and senses physical electrical signals on both differential pairs of the EUSB bus.

摘要： A flash memory controller on a PCIE bus controls flash-memory modules on a flash bus. The flash-memory modules are plane-interleaved using interleaved bits extracted from the lowest bits of the logical block index. These plane-interleave bits are split into a LSB and a MSB, with middle physical block bits between the LSB and MSB. A physical sequential address counter generates a physical block number by incrementing the plane-interleave bits before the middle physical block bits, and then relocating the MSB to above the middle physical block bits. This causes blocks to be accessed in a low-high sequence of 0, 1, 4096, 4097, 2, 3, 4098, 4099, etc. in the four planes of flash memory. A RAM physical page valid table tracks valid pages in the four planes, while a RAM mapping table stores the plane, block, and page addresses for logical sectors generated by the physical sequential address counter.

摘要： An extended Universal-Serial Bus (EUSB) host has reduced loading by using radio frequency (RF) transceivers or direct wiring traces rather than a pair of legacy USB cables. The reduced loading opens the eye pattern. The EUSB device transfers internal data using chained Direct-Memory Access (DMA). Registers in a DMA controller point to a vector table that has vector entries, each pointing to a destination and a source. The source is a memory table for a memory group. The memory table has entries for several memory segments. Each memory-table entry has a pointer to a memory segment and a byte count for the segment. Once all bytes in the segment are transferred, a flag in the entry indicates when another memory segment follows within the memory group. When an END flag is read, then vector table is advanced to the next vector entry, and another memory group of memory segments processed.
