57	Abstract	AB	Systems and methods are disclosed including a first memory device, a second memory device coupled to the first memory device, where the second memory device has a lower access latency than the first memory device and acts as a cache for the first memory device. A processing device operatively coupled to the first and second memory devices can track access statistics of segments of data stored at the second memory device, the segments having a first granularity, and determine to update, based on the access statistics, a segment of data stored at the second memory device from the first granularity to a second granularity. The processing device can further retrieve additional data associated with the segment of data from the first memory device and store the additional data at the second memory device to form a new segment having the second granularity.
