Abstract: Apparatuses are provided for adjusting the write timing. For instance, the apparatus can include an address/control bus, a write clock data recovery (WCDR) signal bus, and a timing adjustment module. The address/control bus can be configured to concurrently enable a WCDR mode of operation and an active mode of operation. The WCDR signal bus can be configured to transmit WCDR data to a memory device during the WCDR mode of operation. And the timing adjustment module can be configured to adjust a timing based on a phase shift in the WCDR data.
