Abstract
A processing device in a memory system determines that data stored in a first block of a plurality of blocks of a memory component satisfies a first threshold criterion pertaining to an age of the data. Responsive to the data stored in the first block satisfying the first threshold criterion, the processing device maintains a first counter to track a number of read operations performed on the first block. The processing device further determines that the data stored in the first block does not satisfy the first threshold criterion, and in response, maintains a second counter to track a number of read operations performed on a super block comprising the plurality of blocks.
