Controlling slew rate performance across different output driver impedances

摘要

Embodiments are provided including one directed to an output driver system, having an adjustable pre-driver configured to maintain a generally constant slew rate of an output driver across a plurality of output driver impedances. Other embodiments provide a method of operating a memory device, including determining an output driver strength of an output driver and configuring the pre-driver based on the determined output driver strength.

主权项

1. An output driver, comprising:
a driver stage, wherein the driver stage can be configured to one of a plurality of output impedances; and a pre-driver circuit coupled the driver stage, wherein the pre-driver circuit can be configured based at least partially on the output impedance.
