Montage Technology Gen2 MRCD and MDB Engineering Samples for DDR5 MRDIMM

Montage Technology announced that it has successfully sampled its Gen2 Multiplexed Rank Registering Clock Driver (MRCD) and Multiplexed Rank Data Buffer (MDB) chipset to leading global memory manufacturers.

Designed for DDR5 Multiplexed Rank DIMM (MRDIMM), this new chipset supports data rates up to 12,800MT/s, delivering memory performance for next-gen computing platforms.

The release comes at a crucial time, as AI and big data analytics drive increasing demands for memory bandwidth in data centers. MRDIMM technology has emerged as a key solution to address this challenge, particularly as server processors continue to increase in core count.

The MRCD and MDB chips are fundamental to MRDIMM operation, featuring a ‘1+10’ buffer architecture where each MRDIMM module incorporates 1 MRCD with 10 MDB chips. In this configuration, the MRCD chip handles buffering and re-driving of address, command, clock, and control signals, while the MDB chips manage data traffic between the memory controller and DRAM chips. This architecture, coupled with double data rate and time-division multiplexing technology, enables simultaneous operation of 2 memory ranks at standard rates, effectively doubling data throughput.

The company’s Gen1 MRCD and MDB chipset, supporting speed up to 8,800MT/s, has already secured volume purchases from major memory manufacturers. The new Gen2 engineering samples push performance boundaries further, achieving 12,800MT/s — a 45% improvement over the previous generation.

“The memory demands of AI and other intensive workloads continue to drive innovation in data center memory architecture,” said Stephen Tai, president, Montage Technology. “Our rapid progression from first-generation production to second-generation sampling demonstrates Montage Technology’s expertise to DDR5 memory technology. This achievement strengthens our position as a leader in memory interface solutions.“

Beyond MRCD and MDB, the firm offers comprehensive memory interface and module support solutions, including RCD, DB, CKD, SPD Hub, PMIC, and TS.

Additionally, the company has begun sampling its Gen5 DDR5 RCD (RCD05) chip in the fourth quarter of 2024, further expanding its industry-leading portfolio. These offerings enable one-stop sourcing for customers while ensuring optimal system integration and performance.
