Primemas Shatters AI Memory Wall at FMS 2026 with CXL Full-Stack Products and Micron Collaboration on the Abaco Project

Business Wire

Showcasing the industry's only end-to-end CXL 3.0 portfolio and a pioneering 100TB-class Abaco Disaggregated Memory System planned for deployment at PNNL

SANTA CLARA, Calif., August 24, 2026--Primemas Inc., a pioneer in next-generation AI memory system architectures and chiplet-based silicon, showcased its latest CXL memory innovations at the Future of Memory and Storage (FMS) 2026. At the event, the company highlighted the industry's most comprehensive CXL memory portfolio and its strategic collaboration with Micron on the Abaco Project, a rack-scale compute system with over 100TB of CXL-attached shared and pooled memory developed for the Department of Energy's Pacific Northwest National Laboratory (PNNL) to power next-generation, large-scale scientific AI, HPC and data-intensive workloads. The Abaco Project is supported by DOE's Office of Science, Advanced Scientific Computing Research program.

As datasets for AI and data-intensive workloads scale beyond traditional hardware boundaries, data centers are severely bottlenecked by static local memory limits. Primemas and Micron Technology are working together to address this fundamental infrastructure challenge by pioneering a new paradigm. Rather than forcing expensive server over-provisioning, the Abaco System Architecture transforms memory into a dynamic, rack-scale infrastructure layer, allowing advanced CPU and GPU compute clusters to seamlessly access hundreds of terabytes of pooled Micron DDR5 memory within a single rack.

Primemas CXL Add-In Cards and Controller Silicon: The Core Engine of the Abaco System Architecture

The Primemas CXL add-in card is a PCIe-based CXL memory expansion card with 14 or 16 RDIMM slots, supporting up to 3.5TB or 4TB of DRAM capacity, respectively, when populated with 256GB RDIMMs. These products, referred to as the PMA14 and PMA16, deliver up to four times the memory capacity per CXL port compared with conventional monolithic alternatives. The CXL add-in cards are scheduled for shipment to Micron in September, where they'll be installed in the Abaco system racks to begin testing, qualification and benchmarking efforts.

While the Abaco rack-based system architecture reflects a collaborative ecosystem integration between several companies, Primemas' advanced controller silicon provides the foundation that enables the architecture. This foundation is Primemas' proprietary Hublet® architecture. Without Primemas' high-density silicon capable of aggregating terabytes of DRAM, the high memory density required by PNNL's advanced scientific AI workloads would not be achievable. Furthermore, by deploying three to four Abaco chassis per server rack, data center operators can build shared memory pools exceeding 100TB, unlocking a new scale of memory infrastructure for AI, HPC, and data-intensive applications.
