Claim 11:
12. A storage device comprising:
a non-volatile memory including a plurality of physical blocks that include a first physical block and a second physical block; and
a controller configured to group the plurality of physical blocks into a plurality of first super blocks such that each of the plurality of first super blocks includes physical blocks that have equal or similar electrical characteristics at a first time period,
wherein the controller is further configured to perform a read operation on each of the plurality of physical blocks using a read level offset based on a difference in electrical characteristics between the physical blocks, and
wherein the controller is further configured to regroup the plurality of physical blocks into a plurality of second super blocks based on a result of the read operation such that each of the plurality of second super blocks includes physical blocks that have equal or similar electrical characteristics at a second time period.
