US Patent 11500582 Trigger margin based dynamic program step characteristic adjustment

Embodiments can include a scan of data associated with programmed memory cells is performed. The scan of data results in a bit error count (BEC) histogram. A trigger margin is determined from the BEC histogram. The determined trigger margin and a target trigger margin are compared. In response to the determined trigger margin being different than the target trigger margin, one or more program step characteristics is adjusted to adjust the determined trigger margin toward the target trigger margin.
