Abstract
A processing device of a memory sub-system is configured to determine, for a memory unit of the memory device, a plurality of write disturb counts associated with the memory unit, wherein each of the plurality of write disturb (WD) count is associated with a corresponding write disturb direction; compute, for the memory unit, a weighted WD count reflecting the plurality of write disturb counts; determine whether the weighted WD count meets a criterion; and responsive to determining that the weighted WD count meets the criterion, perform a refresh operation on the memory unit.
