1. A data processing system, comprising:

  • a memory device operable to maintain a data set;

    a data decoder circuit operable to determine a decoded output based on the data set and provide an iteration count indicating a number of iterations that a data decoding algorithm is applied to the data set; and

    a recycle control circuit operable to compare a frequency of access corresponding to the data set with an access frequency threshold, compare the iteration count to a first iteration threshold when the frequency of access satisfies the access frequency threshold, compare the iteration count to a second iteration threshold different from the first iteration threshold when the frequency of access fails to satisfy the access frequency threshold, and recycle read data corresponding to the data set upon determining the iteration count satisfies the first or second iteration threshold.
