Each cycle of test pattern signals may be transmitted at an adjusted relative phase with respect to a clock also transmitted to the memory device. The memory device may input the test pattern signals at a timing determined by the clock, such as rising and/or falling edges of the clock. The test pattern as input by the memory device may be sent to the memory controller to determine if the test pattern was successfully transmitted to the memory device during the cycle. Multiple cycles of test pattern transmissions are evaluated to determine a relative phase of command/address signals with respect to the clock for transmission during operation of the system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Memory devices, systems and methods employing command/address calibration","description":"During a command/address calibration mode, a memory controller may transmit multiple cycles of test patterns as signals to a memory device.
