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.

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.

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.

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.

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.

Abstract: Methods, systems, and devices for memory management procedures for write boost mode are described. A memory system may receive a command to write data. The memory system may write the data to a first location of the memory system using a first mode for storing one bit per memory cell based on receiving the command. The memory system may select a first portion of the data to rewrite to the memory system using a second mode for storing two or more bits per memory cell based on one or more parameters satisfying one or more thresholds. The memory system may write the first portion of the data to a second location of the memory system using the second mode based on selecting the first portion of the data. The memory system may maintain a second portion of the data at the first location of the memory system.

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.
