RLDRAM® Memory Fuels Next-Gen Networking

Micron has a long history of providing networking customers with outstanding technical expertise, dedicated customer support, and some of the best low-latency memory solutions available. I’m proud that it has led to a technical collaboration with TPACK, now a subsidiary of AppliedMicro, that pairs our low-latency RLDRAM memory with their next-generation TPX5000 100G packet processor to create a highly customizable platform that maximizes networking system performance. TPACK A/S chose our RLDRAM 2 memory for their new Ardbeg reference design for high-speed 100 Gb/s optical transport systems.

It’s a high-performance design meant to help networking equipment meet the ever-increasing demand for bandwidth. TPACK has selected Micron’s RLDRAM 2 as it represents a cost-efficient, high-performing, and well supported memory solution for networking applications. To match the requirements of the networking segment, Micron is committed to providing customers with supply stability and continuity of support.

As a matter of fact, our popular RLDRAM 2 product line was recently migrated to a more advanced 50nm process technology and the Ardbeg platform makes good use of the new design. Moving to 50nm provides enhanced benefits, including improved system performance and lower power consumption. It also allowed us to move production of these parts to our most advanced fabs, which will help us maintain a much longer roadmap for RLDRAM 2 memory, enabling us to provide these parts for years to come. The TPX5000 processor (the newest in TPACK’s line of TPX packet-transport switches) delivers a full 100 Gb/s line rate and is targeted at transport network applications. It provides extensive support of Ethernet and MPLS-TP protocols with HW-based SONET-style OAM and 50ms protection for thousands of individual packet flows.

The addition of Micron’s RLDRAM 2 facilitates lookup in large Ethernet and MPLS-TP address tables at the 100 Gb/s line rate. While we expect RLDRAM 2 be used in applications like this for years to come, we recently also announced our third-generation RLDRAM 3 memory that pushes performance even further with higher densities and lower latency.
