  • Publication number: 20240145010
    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.

  • Patent number: 11972114
    Abstract: A set of threshold voltage distribution width measurements are obtained for a block in a memory device. An endurance estimate is determined for the block based on the threshold voltage distribution width measurements. The endurance estimate comprises an indication of an estimated number of program/erase cycles during which data can be reliably stored by the block. One or more parameters of the block are managed based on the endurance estimate.

  • Patent number: 11922029
    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.

  • Publication number: 20240071522
    Abstract: Methods, systems, and apparatuses include receiving a read command including a logical address. The read command is directed to a portion of memory composed of blocks and each block is composed of wordline groups. The physical address for the read command is identified using the logical address. The wordline group is determined using the physical address. A slope factor is retrieved using the wordline group. A read counter is incremented using the slope factor.

  • Patent number: 11797216
    Abstract: A signal associated with performance of a memory operation can be applied to a memory cell of a first group of memory cells that have undergone PECs within a first range. The signal can have a first magnitude corresponding to a second range of PECs. Whether differences between a first target voltage and the signal and between a second target voltage and the applied signal are at least the threshold value can be determined. Responsive to determining that the differences are at least the threshold value, the first group of memory cells can be associated with a first calibration cluster and the signal having a second magnitude corresponding to a third range of PECs can be applied to a memory cell of a second group of memory cells that have undergone respective quantities of PECs within the second range.

  • Patent number: 11762779
    Abstract: Various embodiments enable read buffering in connection with data block transfer on a memory device. For some embodiments, read buffering from a set of cache blocks is enabled during a period of wait time after data is copied (e.g., data is transferred, such as part of a compaction operation) from the set of cache blocks to a set of non-cache blocks. In various embodiments, after the wait time, data stored on the set of cache blocks is erased (e.g., the set of cache blocks is released) and read buffering from the set of cache blocks is disabled.

  • Publication number: 20230289062
    Abstract: Control logic in a memory device causes a first pulse to be applied to a plurality of word lines coupled to respective memory cells in a memory array during an erase operation. The control logic further causes a second pulse to be applied to a first set of word lines of the plurality of word lines to bias the first set of word lines to a first voltage. The control logic can cause a third pulse to be applied to a second set of word lines of the plurality of word lines to bias the second set of word lines to a second voltage and cause a fourth pulse to be applied to a source line of the memory array to erase the respective memory cells coupled to the first set of word lines and to program the respective memory cells coupled to the second set of word lines.
