Abstract: A method of operation in a memory controller includes operating pull-up and pull-down drivers driven by separate pre-drivers between different voltage rails. Data signals driving the pull-up driver and the pull-down driver are synchronized, and the pull-up driver and the pull-down driver are coupled together to produce an output signal having a voltage swing based on both the pull-up driver and the pull-down driver.

Abstract translation: 存储器控制器中的操作方法包括由不同电压轨之间的分离的预驱动器驱动的操作上拉和下拉驱动器。 驱动上拉驱动器和下拉驱动器的数据信号被同步，并且上拉驱动器和下拉驱动器耦合在一起以产生具有基于上拉驱动器和 下拉驱动程序。
