Original Abstract Submitted

Embodiments disclosed can include determining, for a wordline of the plurality of wordlines, a target read window budget (RWB) increase, wherein the target RWB increase corresponds to a maximum RWB increase associated with using a different PV voltage offset for each respective programming level of a memory cell. Embodiments can also include segmenting the plurality of wordlines into one or more wordline groups, wherein each wordline group comprises one or more wordlines. Embodiments can further include determining, for each wordline group, a target adjustment to a parameter of a memory access operation that is performed with respect to a memory cell associated with a wordline of the wordline group. Embodiments can include determining an aggregate RWB increase for the block in view of the target adjustment to the parameter of the memory access operation. Embodiments can further include determining that the aggregate RWB increase for the block satisfies a threshold range associated with the target RWB increase. Embodiments can also include modifying the parameter of the memory access operation according to the target adjustment.
