Abstract: A processing device in a memory sub-system initiates a partial block handling protocol for a closed block of a memory device, the block comprising a plurality of wordlines. The processing device further sends a first programming command to the memory device to program one or more wordlines of the block with first padding data having a first data pattern, wherein the one or more wordlines are adjacent to a last wordline of the block programmed before the block was closed. In addition, the processing device sends a second programming command to the memory device to program all of a set of remaining wordlines of the block with second padding data having a second data pattern comprising fewer bits of data per cell than the first data pattern.

Abstract: Some embodiments include an assembly having a stack of alternating dielectric levels and conductive levels. Channel material pillars extend through the stack. Some of the channel material pillars are associated with a first sub-block, and others of the channel material pillars are associated with a second sub-block. Memory cells are along the channel material pillars. An insulative level is over the stack. A select gate configuration is over the insulative level. The select gate configuration includes a first conductive gate structure associated with the first sub-block, and includes a second conductive gate structure associated with the second sub-block. The first and second conductive gate structures are laterally spaced from one another by an intervening insulative region. The first and second conductive gate structures have vertically-spaced conductive regions, and have vertically-extending conductive structures which electrically couple the vertically-spaced conductive regions to one another.

Abstract: A system includes a memory device including multiple memory cells and a processing device operatively coupled to the memory device. The processing device is to receive a first read command at a first time. The first read command is with respect to a set of memory cells of the memory device. The processing device is further to receive a second read command at a second time. The second read command is with respect to the set of memory cells of the memory device. The processing device is further to increment a read counter for the memory device by a value reflecting a difference between the first time and the second time. The processing device is further to determine that a value of the read counter satisfies a threshold criterion. The processing device is further to perform a data integrity scan with respect to the set of memory cells.

Abstract: A vertical structure extends through a tiered structure of alternating conductive and insulative materials. The vertical structure includes a channel structure and a tunneling structure. At least one of the conductive materials of the tiered structure provides a select gate tier (e.g., including a control gate for a select gate drain (SGD) transistor). Adjacent the select gate tier of the tiered structure, the tunneling structure consists of or consists essentially of an oxide-only material. Adjacent the word line tiers of the tiered structure, the tunneling structure comprises at least one material that is other than an oxide-only material, such as a nitride or oxynitride. The oxide-only material adjacent the select gate tier may inhibit unintentional loss of charge from a neighboring charge storage structure, which may improve the stability of the threshold voltage (Vth) of the select gate tier.

The controller may be configured to perform the read operation based on the one or more read voltage offsets.

Abstract: Methods, systems, and devices for transient and stable state read operations of a memory device are described. A memory system may implement a read operation including a delay if a channel is at stable state, and may implement a read operation without a delay if the channel is in a transient state. Upon receiving a read command to a set of memory cells sharing the channel, the memory system may determine whether the channel is in a stable or transient state. If the channel is in a stable state, the memory system may perform a read operation including a delay between boosting the channel and driving respective word lines, such that the channel partially discharges prior to driving the word lines. If the channel is in a transient state, the memory system may perform a read operation without a delay between boosting the channel and driving the word lines.
