Micron announced 128GB DDR5 RDIMM memory based on 32Gb monolithic chip

Following the launch of the high-capacity 96GB DDR5 RDIMM with speeds of 4800MT/s in June of this year, Micron has recently unveiled a 128GB DDR5 RDIMM memory module based on a 32Gb monolithic chip, which further elevates the speed to 8000MT/s. This advancement is poised to better meet the performance requirements of various critical task applications within data centers and cloud environments, including artificial intelligence (AI), in-memory databases (IMBD), and various multi-core and multi-threaded productivity scenarios.

This 128GB DDR5 RDIMM memory leverages Micron’s industry-leading 1-beta (1β) technology, and when compared to competitors’ 3DS silicon through-silicon via (TSV) products, offers the following enhancements:

  • An increase in bit density of over 45%
  • An energy efficiency improvement of up to 24%
  • A reduction in latency by as much as 16%
  • An AI training performance boost of up to 28%

Furthermore, Micron’s 32Gb DDR5 memory solution adopts a novel chip architecture designed to achieve leading array efficiency and the most compact monolithic DRAM chip. Voltage domain and refresh management features contribute to optimizing the power delivery network, delivering the energy efficiency performance the market urgently requires. Additionally, Micron has optimized the aspect ratio of the chip size, thereby enhancing the manufacturing efficiency of the high-capacity 32Gb DRAM chips. Micron plans to release 128GB RDIMMs in 2024 starting with models at speeds of 4800MT/s, 5600MT/s, and 6400MT/s, with the 8000MT/s model to follow later.

Executives from AMD and Intel have expressed keen interest in Micron’s new DDR5 RDIMM memory and have incorporated it into the cooperation plans for their next-generation server platforms.
