A data processing system includes a memory and a data processor. The data processor is connected to the memory and adapted to access the memory in response to scheduled memory access requests. The data processor has power management logic that, in response to detecting a memory power state change, determines whether to retrain or suppress retraining of at least one parameter related to accessing the memory based on an operating state of the memory. The power management logic further determines a retraining interval for retraining the at least one parameter related to accessing the memory, and initiates a retraining operation in response to the memory power state change based on the operating state of the memory being outside of a predetermined threshold.
