Abstract
A storage module and method are provided for using healing effects of a quarantine process. In one embodiment, a storage module is provided comprising a controller and a memory. The controller is configured to identify a set of memory cells in the memory that contains a bit error rate above a threshold, wherein the bit error rate is above the threshold due to trapped charge in dielectrics of the memory cells. The controller is also configured to quarantine the set of memory cells for a period of time, wherein while the set of memory cells is quarantined, heat generated by the storage module anneals the set of memory cells to at least partially remove the trapped charge.
