The system combines multiple CXL memory cards into a larger shared pool.\n\nThe two companies are also working together on Abaco, a large-scale shared-memory project for Pacific Northwest National Laboratory, a US Department of Energy research lab.\n\nCXL is a high-speed connection technology that allows processors and accelerators to access memory beyond what is installed in an individual server. Pooling that capacity can help data centers use memory more flexibly across CPU- and GPU-based systems.\n\nThe technology is drawing attention as AI servers require increasingly large amounts of costly memory. Pooled-memory systems allow capacity to be shared across computing systems rather than remaining tied to individual machines.\n\n“Our relationship with Micron is not simply about buying and selling products,” Primemas CEO Park Il said at a media roundtable at the company's research and development center in Seongnam, Gyeonggi Province.\n\n“We are working very closely together, both strategically and technically.”\n\nFounded in January 2023, Primemas is a fabless semiconductor startup headquartered in Santa Clara, California, with its R&D center in Seongnam.\n\n“With Micron, the partnership has taken shape around JBOM and moved into the mass-production stage,” said Jeon Duk-ho, vice president of technology strategy at Primemas.\n\nThe partnership gained further visibility at the Future of Memory and Storage conference in Santa Clara earlier this month, where Primemas was mentioned during a Micron keynote. The companies are also jointly promoting the technology to prospective customers.\n\nTheir cooperation extends to Abaco, a rack-scale system designed to support scientific AI, high-performance computing and other data-intensive workloads at the national lab.\n\nBacked by the DOE's Advanced Scientific Computing Research program, Abaco is designed to provide more than 100 terabytes of CXL-based shared and pooled memory using Micron DDR5. Primemas' CXL add-in cards are scheduled to be shipped to Micron in September for testing, qualification and benchmarking in the system.\n\nJeon said the latest FMS marked a more concrete stage for the project, with the Abaco name, its deployment at the national lab and DOE funding publicly disclosed.\n\nAlongside JBOM, Primemas is developing SLiM, or switchless pooled memory, its architecture for pooling memory capacity without requiring a separate CXL switch. The company is targeting applications including AI inference and key-value cache offloading.\n\nPark said Primemas expects to begin generating revenue in the fourth quarter and reach at least $200 million in cumulative sales by the end of 2027. Unlike a conventional fabless chipmaker, the company sells not only controller chips but also cards, boards and system-level products.\n\nPrimemas ultimately aims to position itself as an AI data infrastructure provider, with pooled memory emerging as a new layer in computing architecture between DRAM and storage.\n\n“I believe pooled memory will become a new layer in computing architecture,” Park said. “The market could eventually grow to rival the size of today's DRAM market.”\n\nyeeun@heraldcorp.com", "url": "https://wpnews.pro/news/primemas-nears-cxl-memory-mass-production-with-micron", "canonical_source": "https://www.koreaherald.com/article/10847286", "published_at": "2026-08-20 09:18:36+00:00", "updated_at": "2026-08-20 09:43:50.927707+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-infrastructure", "ai-chips"], "entities": ["Primemas Inc.", "Micron Technology", "JBOM", "Abaco", "Pacific Northwest National Laboratory", "Park Il", "Jeon Duk-ho", "SLiM"], "alternates": {"html": "https://wpnews.pro/news/primemas-nears-cxl-memory-mass-production-with-micron", "markdown": "https://wpnews.pro/news/primemas-nears-cxl-memory-mass-production-with-micron.md", "text": "https://wpnews.pro/news/primemas-nears-cxl-memory-mass-production-with-micron.txt", "jsonld": "https://wpnews.pro/news/primemas-nears-cxl-memory-mass-production-with-micron.jsonld"}}
