  • Publication number: 20260161507
    Abstract: A system includes a memory device with dies and a processing device coupled to the memory device. The processing device causes a health scan to be performed on a set of memory units residing within one or more dies and updates, for each read sample taken during the health scan of a unit of memory, an assignment to a voltage offset bin of a plurality of voltage offset bins. The processing device tracks, by a memory data structure, the updated assignments to the plurality of voltage offset bins and generates, based on the memory data structure, an error rate distribution of the memory device. In response to determining that a trigger rate (TR) margin value associated with the error rate distribution does not satisfy a threshold value, the processing device causes a data associated with the unit of memory to be refreshed.

  • Patent number: 12640212
    Abstract: The present disclosure configures a system component, such as memory sub-system controller, to perform empty page scan operations. The controller, in response to a request to perform an empty page scan operation, identifies a portion of a set of memory components that is empty and ready to be programmed. The controller generates an order in which to perform the empty page scan operation for a plurality of regions of the identified portion of the set of memory components. The controller determines whether a first region of the plurality of regions in the order fails the empty page scan operation before a second region of the plurality of regions is scanned. The controller terminates the empty page scan operation early to prevent performing the empty page scan operation for one or more remaining regions of the plurality of regions of the identified portion.

  • Patent number: 12572418
    Abstract: A system includes a memory device comprising multiple dies and a processing device coupled to the memory device. The processing device causes a health scan to be performed on a block family of the multiple dies. The processing device updates, for each read sample taken during the health scan, an assignment to a voltage offset bin of a plurality of voltage offset bins. The processing device provides the updated assignments to the plurality of voltage offset bins to a machine learning trigger rate (TR) model. The processing device receives, from the machine learning TR model, a code word error rate (CWER) distribution of the memory device. In response to determining that a TR margin value associated with the CWER distribution does not satisfy a threshold value, the processing device causes a data associated with the block family to be refreshed.
