Abstract

Embodiments of the invention are generally directed to systems, methods, and apparatuses for clock enable (CKE) coordination. In some embodiments, a memory controller includes logic to predict whether a scheduled request will be issued to a rank. The memory controller may also include logic to predict whether a scheduled request will not be issued to the rank. In some embodiments, the clock enable (CKE) is asserted or de-asserted to a rank based, at least in part, on the predictions. Other embodiments are described and claimed.
