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.

Abstract: Systems and methods include capture circuitry configured to capture a write signal from a host device using a data strobe signal from the host device and to output one or more indications of capture of the write signal. Calculation circuitry is configured to receive the data strobe signal, receive the one or more indications of capture, and determine a delay between a first edge of the data strobe signal and receipt of the one or more indications of capture. The systems and methods also include transmission and control circuitry configured to launch subsequent write signals at a time based at least in part on the delay.
