• Careful planning of memory chips or DIMM connectors placement to allow best possible path for routing • Reserve space for pin escape (fanout), termination resistors as well as termination power supplies
Implementing a DDR4 DIMM system •JEDEC standards dictate almost all aspects of DDR4 system which ensures interoperability •List of standards • JESD79-4 : DDR4 SDRAM specs • JESD8-24 : POD12 • JESD82-32 : DB specs • JESD82-31 : RCD specs • JESD248 : NVDIMM specs • SPD4.1.2 : SPD specs • Etc…
Ensure that optimal termination values, signal topology, and trace lengths are determined through simulation for each signal group in the memory implementation. NOTE: In a x4 DRAM mode, the MDM(8:0) signals are no longer available as mask signals but configured in a secondary function as MDQS(17:9) signals.
DDR4 SDRAM is a high-speed dynamic random-access memory internally configured as an 8-bank DRAM for the x16 configuration and as a 16-bank DRAM for the x4 and x8 configurations. The device uses an 8n-prefetch architecture to achieve high-speed oper-ation.
