Abstract

System and method of read deskew training for ×4 mode memory control interface configurations. A read deskew training process includes aligning the two strobe signals serving one byte before deskewing the data bits against their corresponding strobe signals. A deskew setting of a variable delay line associated with the second strobe signal is adjusted to align the second strobe signal with reference to the first strobe signal. By aligning the two strobe signals with respect to each other, the read leveling settings can be common within the byte even the two DQS signals are transmitted to or received from two different memory storage devices.
