Primemas samples first chiplet-based CXL 3.0 SoCs
A fabless specialist in chiplet-based SoCs based on its Hublet architecture, Primemas has announced customer samples of the first Compute Express Link (CXL) memory 3.0 controller.
Primemas has been delivering engineering samples and development boards to select strategic customers and partners, who have played a key role in validating the performance and capabilities of Hublet compared to alternative CXL controllers. Building on this early engagement, Primemas is shipping samples of chiplet-based Hublet SoCs to memory vendors, customers, and ecosystem partners.
While conventional CXL memory expansion controllers are limited by fixed form factors and capped DRAM capacities, Primemas leverages cutting-edge chiplet technology to deliver unmatched scalability and modularity. At the core of this innovation is the Hublet — a versatile building block that enables a wide variety of configurations. A 1×1 single Hublet delivers compact E3.S products supporting up to 512GB of DRAM, while a 2×2 Hublet can support a PCIe add-in-card or CEM products with up to 2TB of DRAM. For hyperscale environments, a 4×4 Hublet powers a 1U rack memory appliance capable of an impressive 8TB of DRAM.
The Hublet platform provides scalable I/O, control, and compute functionality, supporting markets such as CXL, AI, and data analytics.
“We are very encouraged by the excellent feedback from our initial partners, who leveraged Hublet to address the challenges posed by rapidly growing workloads,” said Jay Kim, EVP and Head of Business Development at Primemas. “We’re taking the next major step toward commercialisation through our collaboration with Micron and their CXL AVL program.”

The CXL ASIC Validation Lab (AVL) programme was established by Micron to help bring next-generation CXL controllers to market and achieve maximum reliability and compatibility with its advanced DRAM modules. There are numerous challenges in delivering stable, reliable memory read and write operations while optimising performance and power efficiency in CXL controllers. Through this joint effort, the two companies aim to provide a high-quality, reliable, and world-first CXL 3.0 controller along with the latest high-capacity 128GB RDIMM modules.
“With the rapid adoption of AI, and the corresponding increase in memory-intensive workloads, CXL-based solutions are driving innovations to transform traditional compute platforms,” said Luis Ancajas, director of CXL Business Development at Micron. “As an industry leader in data centre memory, we are collaborating with innovators like Primemas to validate and accelerate next-generation products like the Hublet SoCs through our AVL program and help bring these transformative solutions to market to unlock new levels of performance, scalability and efficiency for the data centre.”
