Reza Unveils Groundbreaking DDR5 MRDIMM Memory Interface Chips with 12800 MT/s Capability

Exciting news is coming from the world of memory technology as new interface chips are set to boost DDR5 MRDIMM speeds to an impressive 12800 MT/s. That’s a significant leap of 4000 MT/s over the original version.

Reza recently unveiled three innovative chips—RRG50120, RRG51020, and RRG53220—designed to support this second generation of DDR5 MRDIMM memory. This positions Reza as a pioneer in offering solutions that push the boundaries of memory bandwidth. Alongside these chips, Reza introduced MRCD, MDB, and PMIC components, not to mention a temperature sensor and SPD hub tailored for MRDIMMs.

So, what makes DDR5 MRDIMM stand out? Unlike standard DDR5 DIMMs or even more advanced options like CUDIMM, MRDIMMs leverage Multiplexer Chips to significantly boost both memory bandwidth and capacity. This enhancement is crucial for high-performance computing systems. By delivering twice the data to the CPU compared to regular DDR5 DIMMs, MRDIMMs are particularly well-suited for AI, HPC, and data center applications where abundant memory bandwidth is essential. Currently, first-gen MRDIMMs can hit 8800 MT/s, almost double the DDR5’s 4800 MT/s.

With Reza’s new chips, the second-gen MRDIMMs can reach an even more impressive 12800 MT/s, marking a leap in performance by roughly 35%. But that’s not the only news. Reza’s MRCD (multichannel refuse close drive) RRG50120 shines with a 45% reduction in power consumption, while the new PMIC chip RRG53220 offers better electrical protection and efficiency. Rounding out the trio is the MDB or Multi-channel Reuse Data Buffer RRG51020. Expect these to hit production in the first half of 2025.

As the need for high-performing systems for AI and HPC continues to swell, Reza has aligned itself with this trend, collaborating with other industry leaders to create next-gen technologies. Reza’s capabilities in expertise and production are a cornerstone for companies looking to keep pace with increasing demands.

“Our latest chip group solution for the second generation DDR5 MRDIMM underlines Reza’s prominent role in this realm,” says Davin Lee, an Executive at Reza.

In terms of design, the TFF MRDIMM offers a larger form factor while maintaining standard module dimensions, allowing for greater memory chip integration and thus higher memory capacity. While MRDIMMs might need a tad more time before reaching the 12000 MT/s threshold, CUDIMMs have already crossed this milestone in mainstream motherboards.

Despite their different applications, both advancements signal a new era of high performance and energy efficiency in both consumer and server technology segments.
