Abstract
An apparatus, such as a memory device, that includes circuits and techniques to synchronize various internal signals with an internal clock signal to ensure proper functionality of the memory device. A walk back circuit is provided to mimic propagation delays of an internal command signal, such as a write command signal, and to speed up the delayed internal command signal an amount equivalent to the propagation delays. The walk back circuit includes a mixture of delay elements provided to mimic propagation delays caused by both gate delays and routing delays.
