Methods and apparatuses for improve data clock to reduce power consumption are presented. The apparatus includes a memory configured to receive a data clock from a host via a link and to synchronize the data clock with the host. The memory includes a clock tree buffer configured to toggle based on the data clock to capture write data or to output read data and a command decoder configured to detect a data clock suspend command while the data clock is synchronized between the host and the memory. The clock tree buffer is configured to disable toggling based on the data clock in response to the command decoder detecting the data clock suspend command. the host includes a memory controller configured to provide a data clock suspend command to the memory via the link while the data clock is synchronized between the host and the memory.
