Abstract
A method includes detecting that a first device in a memory array has degraded, the first device storing a portion of a data record, wherein the data record is encoded using a first error control technique. The method continues with recovering the data record using portions of the data record stored in devices other than the first device in the memory array and encoding the data record using a second error control technique. The method also includes storing the data record in the devices of the memory array other than the first device.
