WebAug 28, 2024 · Fly-by topology reduces SSN by introducing flight-time skew between the address group and point-to-point topology signals of the data groups. Then, the topology matches the timing between the DQS and the clock through a technique called Read-Write Levelization that occurs between the PHY and controller of the device. WebJun 1, 2024 · “Fly by routing” is a popular type of linear daisy chaining used to link multiple DDR3 and DDR4memory chips together, where terminating resistors or stubs are included on each unit to prevent reflection and improve signal integrity. Star A star routing topology involves connecting multiple points to a central hub.
