Fly by topology ddr4

WebSep 23, 2024 · Write Leveling is a DDR3 SDRAM feature that is used to compensate for DQS/CK skew. DDR3 DIMM and multi-component designs must use fly-by topology routing on clocks, address, commands, and control signals. This improves SI, but causes skew between DQS and CK. Write Leveling compensates for this skew. WebKeywords— DDR4, Fly-By topology, series termination, Signal Integrity, Eye diagram, Jitter. I. INTRODUCTION DDR4 technology [1] has enabled single ended signaling at data rates as high as 3.2 Gbps. The two main category of buses involved are the data and address, command and control buses. The data bus comprises several byte lanes.
