Abstract
A host device and memory device function together to perform internal write leveling of a data strobe with a write command within the memory device. The memory device includes a command interface configured to receive write commands from the host device. The memory device also includes an input-output interface configured to receive the data strobe from the host device. The memory device also includes internal write circuitry configured to launch an internal write signal based at least in part on the write commands. The launch of the internal write signal is based at least in part on an indication from the host device that indicates when to launch the internal write signal relative to a cas write latency (CWL) for the memory device.
