The Rambus DDR4 RCD is the key control plane chip which distributes Command\/Address signals and clock to the DRAM devices on the RDIMM. It provides the speed, reliability and power efficiency required for real-time, memory-intensive applications.<\/p>

The DB delivers enhanced performance and margin at 2400 Mbps with built-in support for data rates up to 2666 Mbps. This enables the high speeds and robust operation when multiple LRDIMMs populate the memory channel to deliver the highest system capacities.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

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. Learn about the benefits of DDR5 memory and the design considerations for implementing DDR5 DIMMs.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
