Cadence Advances Memory IP with 12.8 Gbps Gen2 DDR5 MRDIMM Validation on TSMC N3 Process

Cadence today announced the industry's first DDR5 12.8 Gbps MRDIMM Gen 2 memory IP system solution on the TSMC N3 process. The new solution addresses the need for greater memory bandwidth to accommodate unprecedented AI processing demands in enterprise and data center applications, including AI in the cloud. The Cadence DDR5 MRDIMM IP boasts a new high-performance, scalable and adaptable architecture based on Cadence's proven and highly successful DDR5 and GDDR6 product lines. With multiple engagements underway with leading AI, HPC and data center customers, this IP solution is already demonstrating its early leadership.

The new Cadence DDR5 IP offers a PHY and a high-performance controller as a complete memory subsystem. The design is validated in hardware using the most recently available MRDIMMs (Gen 2), achieving a best-in-class 12.8 Gbps data rate that doubles the bandwidth using current DDR5 6400 Mbps DRAM parts. The DDR5 IP memory subsystem is based on Cadence's silicon-proven, high-performance architecture, ultra-low latency encryption and industry-leading RAS features. The DDR5 MRDIMM Gen 2 IP is designed to enable advanced SoCs and chiplets with flexible floor plan design options, while the new architecture allows fine-tuning of power and performance based on individual application requirements.
"The Cadence DDR5 IP portfolio, together with Micron's industry-leading 1γ (1-gamma)-based DRAM, meets the increasing demand for higher memory bandwidth, density and reliability for AI processing workloads. These memory enhancements are pivotal in enabling the next generation AI/ML and HPC applications in data center and enterprise environments," said Praveen Vaidyanathan, vice president and general manager of Micron's Data Center Products.

"Cadence's DDR5 MRDIMM IP system solution, paired with MRDIMM modules featuring Montage's memory buffers, delivers a high-performance memory subsystem for next-generation servers with doubled bandwidth," said Stephen Tai, president at Montage Technology. "Montage's MRCD02/MDB02 chips for MRDIMMs, capable of blazing 12.8 Gbps data rates, are ready to enable server and data center products."

"Data center and enterprise applications stand to gain a significant performance advantage from Cadence's DDR5 12.8 Gbps MRDIMM IP system solution, as evidenced by large customers turning to Cadence to deliver this innovative technology," said Boyd Phelps, senior vice president and general manager of the Silicon Solutions Group at Cadence. "This new leading-edge memory IP system both raises the bar and establishes a roadmap that future-proofs our customers' next-generation SoC and chiplet products for generations to come."

Cadence's DDR5 controller and PHY have been verified with Cadence's Verification IP (VIP) for DDR to provide rapid IP and SoC verification closure. Cadence VIP for DDR5 includes a complete solution from IP to system-level verification with DFI VIP, DDR5 memory model and System Performance Analyzer.

Is this the official JEDEC MRDIMM or the current Intel rebranded MCRDIMM?

This title incorrectly suggests that the memory itself is manufactured using the 3nm process. However, in reality, DRAM is produced using a different process node than the one used for CPUs.

Can someone explain this please.
As my current understanding is
6000mt/s is 48 Gb/s
6400mt/s is 51.2 Gb/s

But they wrote "current 6400 Mb/s Dram parts" and reaching smoking fast 12.8Gb/s??

what am I missing??

All values must be in Mega, on in Giga transfers. How this is calculated to GB/s in article I don't know. :D

DenverCadence doesn't manufacture DRAM itself; it only provides PHY, memory controllers, and related IP.
Exactly, and it would be better to mention "memory controller IP" in the title (even if leaving out PHY).

This here is DDR5-12800 versus the old DDR5-6400. A single memory module would move 204.8 gigabytes per second, and the tech is aimed at big processors with 12-channel memory totalling 2.4 TB/s! AI will gladly consume it all.

Then there is nothing but a typo fest to read.
