Claim 2:
3. The apparatus of claim 2, wherein:
the GCU is a first GCU and the physical data address constitutes a first portion of the first GCU;
the quarantine module is further configured to:
migrate valid from the first GCU to a different, second GCU within the non- volatile memory;
perform an erase operation upon the first GCU to reset memory cells therein;
reduce an overall data storage capacity of the first GCU by excluding the first portion of the GCU while using remaining portions of the first GCU to service data access requests;
scan the first portion of the first GCU to reset at least one reference voltage; and
reincorporating the first portion back into the first GCU responsive to the reseting of the at least one reference voltage; and

the quarantine module further comprises an error circuit configured to alter an error granularity in response to an error rate of the non-volatile memory.
