Abstract
A data processor, system, method, integrated circuit are provided which update timing values for accessing a memory to compensate for voltage and temperature (VT) drift during operation. The method includes performing a link retraining sequence for a plurality of DQ lanes of the memory bus and determining a first phase offset based on the link retraining. The method includes calculating a second offset based on the first offset, applying the second offset to a plurality of command CA lanes of the memory bus.
