China's Montage Technology Achieves Mass Production of DDR5 Fifth-Generation RCD Chip

en.Wedoany.com Reported - On September 28, Montage Technology announced that its DDR5 fifth-generation registering clock driver chip, RCD05, has entered mass production. The chip is primarily used in high-performance DDR5 RDIMM server memory modules, supporting data transfer rates of up to 8000 MT/s, and is designed for memory systems in data centers, AI servers, and other high-performance computing platforms.

RCD05 corresponds to the DDR5 fifth-generation RCD product. According to Montage Technology's disclosed product iteration data, its fourth-generation RCD supports up to 7200 MT/s, while the fifth generation increases this to 8000 MT/s, representing a transfer rate improvement of approximately 11.1%. The company launched the fifth-generation product in the fourth quarter of 2024, completed development of the mass production version in 2025, and continued to advance commercial deployment of the product after the first quarter of 2026.

RCD chips are deployed in DDR5 RDIMM memory modules, where they buffer and drive command, address, and clock signals between the host memory controller and DRAM devices. Montage Technology's current DDR5 RCD products cover multiple generations, including 4800 MT/s, 5600 MT/s, 6400 MT/s, 7200 MT/s, and 8000 MT/s. In June of this year, the company also began sampling its sixth-generation RCD06 to customers, which supports data transfer rates of 9200 MT/s and has entered the validation process with major memory customers.

According to its 2026 semi-annual report, Montage Technology's DDR5 fifth-generation product corresponds to 8000 MT/s, while the sixth generation corresponds to 9200 MT/s. The company also participates in the formulation of international DDR5 RCD standards, and its memory interface chip products target the server and data center memory module markets.
