Abstract
In one embodiment, a system maintains metadata associating each block of a plurality of blocks of the memory device with a corresponding frequency access group, where each frequency access group is associated with a corresponding scan frequency. The system determines that a first predetermined time period has elapsed since a last scan operation performed with respect to one or more blocks of the memory device, where the first predetermined time period specifies a first scan frequency. The system selects, based on the metadata, at least one block from a first frequency access group associated with the first scan frequency. The system performs a scan operation with respect to the selected block.
