  • Publication number: 20240158274
    Abstract: The application discloses a processing method for graphite acid purification wastewater which comprises processing steps of neutralization and precipitation preprocessing, supernatant electrically distilling and vaporizing, electric energy recycling, condensate recycling and vaporization residue regularly discharging. The processing method performs neutralization and precipitation preprocessing to obtain neutralized supernatant, pumps the supernatant into an electric distiller to be vaporized and obtain electric energy for recycling through steam turbine, and acquires vaporization condensate by residual heat exchange. The vaporization condensate reaches the standard of graphite acid purification impurities such as fluorine, chlorine, aluminum, silicon, iron, magnesium, copper, and zinc and the wastewater discharge standard. The steam heat energy can be recycled and transformed into electric energy to save processing cost.

  • Publication number: 20190294345
    Abstract: A Green NAND SSD (GNSD) controller receives reads and writes from a host and writes to flash memory. A SSD DRAM has a DRAM Translation Layer (ETL) with buffers managed by the GNSD controller. The GNSD controller performs deduplication, compression, encryption, high-level error-correction, and grouping of host data writes, and manages mapping tables to store host write data in the SSD DRAM to reduce writes to flash memory. The GNSD controller categorizes host writes as data types for paging files, temporary files, meta-data, and user data files, using address ranges and file extensions read from meta-data tables. Paging files and temporary files are optionally written to flash. Full-page and partial-page data are grouped into multi-page meta-pages by data type before storage by the GNSD controller. Status bits include two overwrite bits indicating frequently-written data that is retained in the SSD DRAM rather than being flushed to flash and re-allocated.

  • Patent number: 9841911
    Abstract: A Green NAND Device (GND) driver application queries AC line and battery status and then stores an image of processor states and caches and a resume routine to DRAM when power failure occurs. A DRAM image is then stored to flash memory for a persistent mode when battery power is available. The image in DRAM may be a partial image that includes entries, flushed caches, processor contexts, ramdisks, write caches, and a resume context. Endurance of flash memory is increased by a Super Enhanced Endurance Device (SEED) SSD. In a power down mode, the GND driver limits DRAM use and only caches in DRAM data that can be deleted on power down. Host accesses to flash are intercepted by the GND driver and categorized by data type. Paging files and temporary files cached in DRAM are optionally written to flash.

  • Patent number: 9720616
    Abstract: A Green NAND SSD Driver (GNSD) driver executes on a host to increase data-retention of flash memory attached to a Super Enhanced Endurance Device (SEED) or Solid-State Drive (SSD). Host accesses to flash are intercepted by the GNSD driver using upper and lower-level filter drivers. A retention-check timer causes a retention routine to be periodically executed. The routine sends high-level commands to the SEED that causes the SEED to refresh either all data or just data blocks with older write dates. Data is refreshed by moving to a new physical block. The retention routine can track write dates of logical blocks and command a SSD to move logical blocks with older write dates. A retention card has a controller that performs the retention routine when not connected to a host, while a SEED power card allows the SEED to refresh data when no host is attached to the SEED.

  • Patent number: 9601508
    Abstract: An alternating stack of insulating layers and sacrificial material layers is formed over a substrate. After formation of a memory opening, all surfaces of the memory opening are provided as silicon oxide surfaces by formation of at least one silicon oxide portion. A silicon nitride layer is formed in the memory opening. After formation of a memory stack structure, backside recesses can be formed employing the silicon oxide portions as an etch stop. The silicon oxide portions can be subsequently removed employing the silicon nitride layer as an etch stop. Physically exposed portions of the silicon nitride layer can be removed selective to the memory stack structure. Damage to the outer layer of the memory stack structure can be minimized or eliminated by successive use of etch stop structures. Electrically conductive layers can be subsequently formed in the backside recesses.

  • Patent number: 9548108
    Abstract: A Virtual-Memory Device (VMD) driver and application execute on a host to increase endurance of flash memory attached to a Super Enhanced Endurance Device (SEED) or Solid-State Drive (SSD). Host accesses to flash are intercepted by the VMD driver using upper and lower-level filter drivers and categorized as data types of paging files, temporary files, meta-data, and user data files, using address ranges and file extensions read from meta-data tables. Paging files and temporary files are optionally written to flash. Full-page and partial-page data are grouped into multi-page meta-pages by data type before storage by the SSD. Ramdisks and caches for storing each data type in the host DRAM are managed and flushed to the SSD by the VMD driver. Write dates are stored for pages or blocks for management functions. A spare/swap area in DRAM reduces flash wear. Reference voltages are adjusted when error correction fails.

  • Patent number: 9547589
    Abstract: 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.

Host accesses to flash are intercepted by the controller and categorized as data types of paging files, temporary files, meta-data, and user data files, using address ranges and file extensions read from meta-data tables. Paging files and temporary files are optionally written to flash. Full-page and partial-page data are grouped into multi-page meta-pages by data type in the DRAM before storage by lower-level flash devices such as eMMC, UFS, or iSSD. Caches in the DRAM buffer for storing each data type are managed and flushed to the flash devices by the controller. Write dates are stored for pages or blocks for management functions. A spare/swap area in DRAM reduces flash wear. Reference voltages are adjusted when error correction fails.
