The present disclosure relates to a system which includes a memory controller interface, a memory unit interface, and a correction block. The memory controller interface includes a digitally-controlled delay line (DCDL). The memory unit interface is coupled to the memory controller interface, and is configured to communicate with the memory controller interface through a first signal and a second signal. The correction block is configured to determine a result of alignment between the first signal and the second signal, and to provide a correction signal configured to align the first signal to the second signal. Other systems, devices and methods are disclosed.
