Abstract: A mechanism is described for facilitating write tracking for following data eye movements across changing thermal conditions in memory systems according to one embodiment of the invention. A method of embodiments of the invention includes monitoring movements of a valid data eye associated with a memory device of a plurality of memory devices of a memory system at a computing system. The monitoring may include initiating write commands during one or more refresh periods associated with the valid data eye. The method may include determining drifting in the movement of the data eye, and correcting the drifting based on adjusting one or more existing phase interpolator values associated with the movements of the data eye.
