Driver circuit |
摘要 |
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. |

1. A method of operation in a memory controller, the method comprising:
operating a pull-up driver within a first voltage swing range; operating a pull-down driver within a second voltage swing range that is not coterminal with the first voltage swing range, synchronizing data signals driving the pull-up driver and the pull-down driver, and producing an output signal having a voltage swing based on a coupled configuration of the pull-up driver and the pull-down driver. |
