Abstract: A processing device determines difference error counts that are indicative of relative widths of valleys. Each of the valleys is located between a respective pair of programming distributions of a memory cell of the memory component. A program targeting operation is performed on the memory cell to calibrate one or more program verify (PV) targets associated with the programming distributions. To perform the program targeting operation, a rule from a set of rules is selected based on the difference error counts. The set of rules corresponds to an adjusting of a PV target of a programming distribution adjacent to an initial programming distribution. One or more program verify (PV) targets associated with the programming distributions are adjusted based on the selected rule.

Abstract: First and second vectors each respectively having first and second magnitudes and first and second phase angles relative to a reference axis are determined by a processing device based on a set of error values corresponding a current processing level for processing data in memory operations on memory cells of a memory component. An estimated processing level offset is generated based on a comparison between at least one of a difference between the first magnitude and the second magnitude or a difference between the first phase angle and the second phase angle. An updated processing level is generated based on the estimated processing level offset, and the updated processing level replaces the current processing level.

Abstract: Aspects of the present disclosure are directed to performing varying frequency memory sub-system background scans using either or both a timer and an I/O event limit. This can be accomplished by identifying a background scan trigger event from one of multiple possible types of background scan trigger events, such as a timer expiration or reaching an event count limit. In response to the background scan trigger event, a background scan can be initiated on a memory portion. The background scan can produce results, such as CDF-based data. When a metric based on the results exceeds a background scan limit, a refresh relocation can be performed and logged. A metric can be generated based on the CDF-based data, obtained error recovery depth data, or refresh relocation event data. When the metric is above or below corresponding background scan thresholds, a background scan frequency can be adjusted.
