Abstract
Systems and methods are disclosed including a memory device and a processing device operatively coupled to the memory device. The processing device can perform operations including identifying, among a first plurality of wordlines of a set of pages of the memory device, at least one wordline having a current value of a data state metric satisfying a first condition; determining new values of the data state metric of a second plurality of wordlines of the set of pages, wherein the at least one wordline is excluded from the second plurality of wordlines; and responsive to determining that the new values of the data state metric of one or more wordlines of the second plurality of wordlines satisfy a second condition, performing a media management operation with respect to the one or more wordlines.
