Non-volatile memory and processes for reprogramming data posing a potential reliability concern are provided. A process is provided for distinguishing between cross-temperature effects and read disturb effects as part of determining whether to perform a maintenance operation such as reprogramming. A process is provided that compensates for cross-temperature effects while testing to determine whether to perform a maintenance operation. Applying temperature compensation attempts to remove cross-temperature effects so that testing accurately detects whether read disturb has occurred, without the effects of temperature. By reducing cross-temperature effects, maintenance operations can be more accurately scheduled for memory that has experienced read disturb, as opposed to cross-temperature effects.
