Start with the requirement
Select the memory generation supported by the processor and board architecture. Include organization, supported rates and the controller vendor qualification requirements.
Technical context
The Micron DDR4 catalog records interface generation, I/O voltage, data rate, bus width and ball count as separate selection attributes. Those fields must all be considered.
Procurement review
DDR4 and DDR5 require different platform support. A higher generation is not an automatic replacement. Use the processor documentation and exact manufacturer datasheets for design approval.
