Abstract:

Dynamic memory performance throttling. An embodiment of a memory device includes a memory stack including coupled memory elements; the memory elements including multiple ranks, the plurality of ranks including a first rank and a second rank, and a logic device including a memory controller. The memory controller is to determine an amount of misalignment between data signals relating to a read request for the first rank and a read request for the second rank, and, upon determining that misaligment between the first rank and the second rank is greater than a threshold, the memory controller is to insert a time shift between a data signal for the first rank and a data signal for the second rank.
