  • Patent number: 11640346
    Abstract: A method includes monitoring a temperature of a memory component of a memory sub-system to determine that the temperature of the memory component corresponds to a first monitored temperature value; writing data to the memory component of the memory sub-system while the temperature of the memory component corresponds to the first monitored temperature value; determining that the first monitored temperature value exceeds a threshold temperature range; monitoring the temperature of the memory component of the memory sub-system to determine that the temperature of the memory component corresponds to a second monitored temperature value that is within the threshold temperature range; and rewriting the data to the memory component of the memory sub-system while the temperature of the memory component corresponds to the second monitored temperature value.

  • Publication number: 20220351762
    Abstract: Methods, systems, and devices for skipping pages for weak wordlines of a memory device during pre-programming are described. A memory device may be configured to operate in a first mode involving skipping one or more pages (e.g., a lower page (LP)) associated with a set of wordlines. In some examples, a testing system may determine the set of wordlines (e.g., weak wordlines) for which to skip pages according to performance degradation for the wordlines in response to applying a threshold temperature to a test memory device. In the first mode, the memory device may store (e.g., pre-program) data in a subset of pages distinct from the skipped pages. The memory device may switch to a second mode in response to a trigger condition. In the second mode, the memory device may use each page associated with the wordlines and may refrain from skipping the one or more pages.
