Abstract: Aspects of the present disclosure configure a system component, such as memory sub-system controller, to perform empty page scan operations. The controller selects a portion of the set of memory components that is empty and ready to be programmed. The controller reads one or more signals from the selected portion of the set of memory components. The controller generates an error count value representing whether the portion of the set of memory components is valid for programming based on a result of reading the one or more signals from the selected portion. The controller updates a scan frequency for performing the empty page scan operations for the portion of the set of memory components based on the error count value.

Abstract: In a non-volatile memory system that performs programming of selected memory cells (in coordination with pre-charging and boosting of channels for unselected memory cells) and program-verify to determine whether the programming was successful, the system transitions from program-verify to the next dose of programming by concurrently lowering a voltage applied to a selected word line and voltages applied to word lines on a first side of the selected word line at the conclusion of program-verify.
