  • Patent number: 12591518
    Abstract: Methods, systems, and devices for validity mapping techniques are described. A memory device may use a change log to update a mapping that indicates whether data stored at respective physical addresses is valid. For example, the memory device may receive a command associated with data having a corresponding set of addresses (whether logical block addresses or physical addresses). The memory device may set an entry of the change log based on whether the set of addresses are consecutive. For example, the memory device may identify whether the set of addresses are consecutive and may set a flag in the entry of the change log to indicate whether the addresses are consecutive. Then, the memory device may update one or more entries of the mapping corresponding to the entry of the change log to indicate whether the addresses corresponding to the one or more entries of the mapping store valid data.

  • Patent number: 12585580
    Abstract: Methods, systems, and devices for techniques for a fragment cursor are described. A memory system may receive one or more write commands, each write command corresponding to a data fragment. The memory device may store the data fragments to a cursor (e.g., a fragment cursor) in a cache upon receiving the write commands, the cursor configured to store data fragments with a size less than a fragment size threshold (e.g., a page). The memory system may detect a memory management operation (e.g., power down, cache synchronization, data relocation, etc.) and write the cached data fragments to a block of memory cells of a memory device using the cursor. In some examples, the cursor may have a different associated mapping unit than other cursors of the memory system.

  • Publication number: 20260082674
    Abstract: The present application discloses a fabrication method for an integrated structure of transistors with different operating voltages. A high-voltage transistor area and a low-voltage transistor area are protected by a retained hard mask layer before a medium-voltage gate oxide layer is grown, so as to avoid additional growth of gate oxide layers above active areas of the high-voltage transistor area and the low-voltage transistor area, thereby avoiding the deterioration of a step height of the low-voltage transistor area due to the subsequent use of a large amount of acid to remove the gate oxide layer additionally grown above the active area of the low-voltage transistor area, and preventing the electrical property and the reliability of a low-voltage device from being subsequently influenced while avoiding the influence of the etching with the large amount of acid on the thickness of a high-voltage gate oxide layer which has already been grown.

  • Patent number: 12574664
    Abstract: This application discloses a CIS pixel readout circuit structure. An SG and an SF adopt different transverse thicknesses of spacers. The spacer of the SG adopts a smaller transverse thickness to reduce the parasitic resistance. The spacer of the SF adopts a larger transverse thickness to reduce the GIDL current. In the CIS pixel readout circuit structure according to this application, drain metal plugs are formed on outer sides of both left and right ends of an SF gate structure. The SF and the SG form a T-shaped combined compact structure to achieve equivalent parallel connection of two SF, thus effectively reducing the parasitic resistance of the share active area between the SG and the SF, and simultaneously saving the space area. This application further discloses a method for fabricating a CIS pixel readout circuit structure.

  • Patent number: 12430260
    Abstract: Methods, systems, and devices for a sorted change log for physical page table compression are described. A mapping between a logical address and a physical address may be stored in a change log buffer. The mapping may be stored at a location of the change log buffer based on the logical address of the mapping relative to logical addresses of other mappings stored in the change log buffer. Based on storing mappings in the change log buffer based on logical addresses of the mappings, a set of mappings in the change log may include a set of sequentially-indexed logical addresses. A compressed entry for a logical-to-physical table may be generated based on the set of mappings.

  • Publication number: 20250151424
    Abstract: This application discloses a CIS pixel readout structure. An SF and an SG adopt an asymmetric spacer structure, so that the pitch from a lower end of a source metal plug of the SG to SG gate poly can be reduced while keeping the pitch from a lower end of a drain metal plug of the SF to SF gate poly unchanged, thus reducing the pitch from a drain connecting point of the SF to a source connecting point of the SG. Since a source of the SG is not connected with working voltage and it is not influenced by leakage, not only can GIDL current be maintained, but also parasitic resistance can be reduced. Without changing its effective size, it can reduce the parasitic resistance effect while reducing the area of a combined structure of the SF and the SG.

  • Publication number: 20240394196
    Abstract: Methods, systems, and devices for logical-to-physical (L2P) mapping compression techniques are described. A memory system may use an L2P mapping to map logical addresses to physical addresses of the memory system. The L2P mapping may be a hierarchical L2P mapping divided into multiple levels or subsets that are used to identify a physical address corresponding to a logical address. The memory system may write data to a set of physical addresses that are consecutively indexed and may set a flag in an entry of a second-level of the L2P mapping (e.g., of a three-level L2P mapping) to indicate that the entry is associated with a starting physical address of the consecutively indexed physical addresses. The memory system may subsequently read the data starting at the starting physical address based on the flag (e.g., bypassing reading an entry of a lowest-level of the L2P mapping to determine the physical address).

  • Publication number: 20240382412
    Abstract: A bioorthogonal catalytic patch integrates TiO2 nanosheets populated with metallic nanoparticles into polyvinyl alcohol-based microneedles arranged in an array. This bioorthogonal patch-based device is robust, removable and can effectively mediate the conversion of caged substrates into their active states once placed at the site of application. The capacity of the patch in executing bioorthogonal catalysis in high-level living systems was demonstrated by localized dealkylation of a caged doxorubicin prodrug at the melanoma tumor site and restoration of its pharmacological properties for cancer therapy. This in situ applied patch facilitated to enhance the local treatment efficacy and eliminate off-targeted prodrug activation or dose-dependent side effect towards healthy organs or tissues located away from the application site.
