    摘要: An apparatus and method are disclosed. In one embodiment, the apparatus trains a memory link using a signal alignment unit. The signal alignment unit aligns a read data strobe signal that is transmitted on the link with the center of a read data eye transmitted on the link. Next, the signal alignment unit aligns a receive enable signal that is transmitted on the link with the absolute time that data returns the data lines of the link a column address strobe signal is sent to the memory coupled to the link. Next, the signal alignment unit aligns a write data strobe signal transmitted on the link with the link's clock signal. Finally, the signal alignment unit aligns the center of the write data eye transmitted on the link with the write data strobe transmitted on the link.

    摘要: Embodiments of the invention are generally directed to systems, methods, and apparatuses for suppressing power supply noise using data scrambling in double data rate memory systems. In some embodiments, an integrated circuit includes a transmit data path to transmit data to one or more memory devices. The transmit data path may include scrambling logic to generate, in parallel, N pseudo random outputs that are uncorrelated with each other. The output data and the pseudo random outputs are input to XOR logic. The transmit data path transmits the output the of XOR logic which has a substantially white frequency spectrum. Other embodiments are described and claimed.
