Abstract
A method, system, and computer program product are provided for adjusting write timing in a memory device based on a command protocol. For instance, the method can include enabling a write clock data recovery (WCDR) mode of operation. The method can also include transmitting WCDR data from a processing unit to the memory device during the WCDR mode of operation and another mode of operation of the memory device. Based on a phase shift in the WCDR data, a phase difference between a signal on a data bus and a write clock signal can be adjusted. Further, the method can include transmitting the signal on the data bus based on the adjusted phase difference between the signal on the data bus and the write clock signal.
