Abstract
Systems and methods for managing data in non-volatile memory devices across a large range of operating temperatures are provided. Embodiments discussed herein selectively reprogram previously programmed data at a temperature that better enables the data to be read regardless of where within the range of operating temperatures the data is being read. Circuitry and methods discussed herein can keep track of a program temperature associated with each portion of non-volatile memory and use this information along with other criteria to selectively perform temperature based moves of data. This enables a mechanism for data to programmed in out-of-bounds temperature ranges to be reprogrammed within an in-bounds temperatures range so that a temperature delta between the reprogrammed temperature and the read operation temperature is below a threshold that ensure efficient and error free read operations to be performed.
