1. A system comprising:
a memory device organized into multiple word line groups, each word line group of the multiple word line groups comprising one or more word lines; and
a processing device, operatively coupled with the memory device, to perform operations comprising:
detecting a read operation directed at the memory device;
identifying a word line corresponding to a read location of the read operation based on a stored mapping between read locations and word lines in the memory device;
identifying a word line group from among the multiple word line groups to which the word line belongs based on a stored mapping between word lines and the multiple word line groups;
incrementing a read counter associated with the word line group based on the read location of the read operation corresponding to the word line from the word line group;
determining the read counter exceeds a read-disturb threshold; and
in response to determining the read counter exceeds the read-disturb threshold, performing read-disturb handling on the word line group.
