Abstract:
1. A method of operation in a system that includes a controller, a first memory device and a second memory device, the method comprising: storing a first phase adjustment value in a first register disposed on the controller, the first phase adjustment value representing a transmit phase adjustment that is based on a flight time of first data propagating from the controller to the first memory device; storing a second phase adjustment value in a second register disposed on the controller, the second phase adjustment value representing a transmit phase adjustment that is based on a flight time of second data propagating from the controller to the second memory device; the controller transmitting the first data to the first memory device in accordance with the first phase adjustment value; the controller transmitting the second data to the second memory device in accordance with the second phase adjustment value; and determining the first phase adjustment including synchronizing an adjusted clock signal to a clock signal from the first memory device.
