Abstract
A description of deskewing data from the clock from a DRAM, such as, but not limited to a DDR3 DRAM is discussed. For example, the differential signals of a strobe and a clock signal are used to create a first and second loops that can be fed back to a memory controller. The two loops are then compared and a delay is added to the strobe until it matches the delay time of the clock.
