One clock training sweep operation is performed to determine phase relationships for two write clocks with respect to a command clock. The phase relationships are generated to satisfy timing requirements for two different client devices, such as GDDR5 DRAM components. A second clock training sweep operation is performed to better align local clocks operating on the client devices. A voting tally is maintained during the second clock training sweep to record phase agreement at each step in the clock training sweep. The voting tally then determines whether one of the local clocks should be inverted to better align the two local clocks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hardware WCK2CK training engine using meta-EDC sweeping and adjustably accurate voting algorithm for clock phase detection","description":"One embodiment of the present invention sets forth a technique for performing high-performance clock training.
