How the DDR5 Server DIMM Chipset Works

Our Server DIMM Chipset will enable increased memory capacity, while maintaining peak performance on a dual inline memory module (DIMM). These gains are essential for tomorrow’s most grueling data-intensive applications.

DDR5 data buffers (DB) and DDR5 registering clock drivers (RCD), are targeted for use in DDR5 Registered DIMMs (RDIMMs) and DDR5 Load Reduced DIMMs (LRDIMMs), to deliver higher bandwidth, performance and capacity versus unbuffered DIMMs. RDIMMS and LRDIMMs reduce load on the CPU and improve the signal integrity of the command/address bus. Specifically, the DDR5 DB will reduce the effective load on the data bus, which enables higher-capacity DRAMs on the module without reducing latency.

DDR5 will significantly increase capacity and speed from DDR4 and DIMM chipsets offer enhanced performance and margin with this new memory standard.

About DDR5

DDR5 is a working DRAM standard being created by JEDEC and is the next evolutionary step from DDR4. The new features in DDR5 will target the specific problems being caused by the exponential growth in data generated by IoT, cloud services and real-time data analytics, and address the need to continuously process, move, and analyze that data faster. These enhancements are expected to include higher density, a new command structure and new power saving features. DDR5 will also likely introduce signal equalization and error correction.

Data Center Evolution: DDR5 DIMMs Advance Server Performance

Driven by a confluence of megatrends, global data traffic is increasing at an exponential rate. For example, 5G networks are enabling billions of AI-powered IoT devices untethered from wired networks. Nowhere is the impact of all this growth being felt more intensely than in data centers. Indeed, hyperscale data centers have become the critical hubs of the global data network. DDR5 DRAM will enable the next generation of server systems providing the massive computing power of hyperscale and enterprise data centers.

High Speed Memory Interface Chipsets Let Server Performance Fly

High Speed Memory Interface Chipsets Let Server Performance Fly

The demands on server performance continue to increase at a tremendous pace. New requirements from large in-memory databases that are powering today’s cloud services and advanced analytics tools are arriving just as the impact of Moore’s Law is starting to slow. One key new opportunity is for high-speed server memory interface chipsets, which enable high-speed memory performance without compromising on memory capacities. Companies looking to optimize their server memory architecture designs, and improve their overall server performance and reliability, should give serious consideration to optimized DDR4 memory interface chipsets, which enhance the performance of server memory modules.
