Abstract
An integrated circuit (IC) memory controller is disclosed. The memory controller includes a receiver to receive a strobe signal and provide an internal strobe signal. An adjustable delay circuit delays an enable signal to generate a delayed enable signal. A gate circuit generates a gated strobe signal using the delayed enable signal that masks transitions of the internal strobe signal that occur prior to a valid region of the internal strobe signal. A sample circuit samples data using the gated strobe signal.
