Classification: CPC G | IPC G

Claim 6:
7. A data storage device, comprising:
a memory device, wherein the memory device is arranged into a first super device having a first plurality of active zones and a second super device having a second plurality of active zones; and
a controller coupled to the memory device, the controller configured to:
determine that the first super device is below a threshold limit, wherein the threshold limit is the minimum free space to be maintained within the first super device; and
move data from at least one zone of the second plurality of active zones of the second super device to at least one other zone of the first plurality of active zones of the first super device in response to the determining, wherein:
moving the data from the at least one zone of the second plurality of active zones of the second super device to the at least one other zone of the first plurality of active zones of the first super device is further in response to determining that the threshold limit of the second super device has been reached or exceeded;
the data corresponds to data of a cold zone, wherein the cold zone is a zone that has a number of resets less than a predetermined zone reset threshold;
a hot zone is a zone that has a number of resets greater than the predetermined zone reset threshold; and
the cold zones are consolidated to a super device designated for cold zones.
