Servers And The Drive to DDR5

DDR5 will be essential to meet the average server’s DRAM needs.


This IDC Technology Spotlight Study, sponsored by Rambus, discusses server demands on DRAM and different workloads. DRAM must dynamically adjust to the needs of these disparate workloads. The history of dynamic random-access memory (DRAM) is characterized by the ability of the technology to adapt to the increasingly specialized real-time memory requirements of the applications that utilize it. The COVID-19 pandemic changed the average DRAM content by workload balance in servers. While workloads require servers to adapt to their specific needs, servers must be based on standardized, scalable technologies to be affordable. Over time, DDR5 will be essential to meet the average server’s DRAM needs.

This study discusses:

  • The server market does not switch new DRAM generations until it must
  • DRAM transitions take an increasingly long time to enable each new generation
  • An ecosystem of organizations has worked on DDR for more than five years, including: The Joint Electron Device Engineering Council (JEDEC), memory controller vendors, data processing vendors, DRAM chip vendors, module vendors, buffer vendors, and system makers
  • As demand continues to rise for DDR5, benefits include:
    • Speed
    • Power consumption
    • Power management
    • Signal integrity
    • Memory efficiency
    • Capacity
