  • Optimal data eye for improved Vref margin
    Patent number: 9971975
    Abstract: An optimized method, system, and apparatus for determining optimal DQS delay for DDR memory interfaces are disclosed. The method performs data eye training in a two dimensional space with time delay value as x-axis and reference voltage (Vref) as y-axis to determine a rectangular data eye within an overall data eye with Vref margin.
    Type: Grant
    Filed: March 23, 2017
    Date of Patent: May 15, 2018
    Assignee: Invecas, Inc.
