Marvell Extends CXL Ecosystem Leadership with Structera Interoperability Across All Major Memory and CPU Platforms

Rhea-AI Summary

Marvell Technology (NASDAQ: MRVL) has achieved a significant milestone with its Structera CXL memory-expansion controllers completing interoperability testing with DDR4 and DDR5 memory solutions from Micron, Samsung, and SK hynix. This follows previous successful testing with AMD EPYC and Intel Xeon platforms, making Structera the only CXL 2.0 product family fully tested across major CPU architectures and memory suppliers.

The Structera product line features two families: Structera A with 16 Arm Neoverse V2 cores for high-bandwidth memory applications, and Structera X for memory expansion in general-purpose servers. Both product families are industry-first with four memory channels, inline LZ4 compression, and 5nm manufacturing processes.

Insights

Semiconductor Industry Analyst

Marvell's Structera achieves industry-first CXL interoperability across all major platforms, strengthening its competitive position in memory solutions.

Marvell's announcement represents a significant technical milestone in the evolving Compute Express Link (CXL) ecosystem. By achieving interoperability with both DDR4 and DDR5 memory from Micron, Samsung, and SK hynix, as well as with AMD EPYC and Intel Xeon platforms, Marvell has established its Structera product line as the only CXL 2.0 solution with this comprehensive compatibility.

This cross-platform validation solves a critical pain point for hyperscalers who require seamless integration across diverse memory configurations and CPU architectures. The technical achievement reduces integration risk and qualification timelines for OEMs and cloud providers, while preserving supply chain flexibility—a particularly valuable advantage given recent memory supply constraints.

What sets Structera apart technically is its dual-product approach: the Structera A incorporates 16 Arm Neoverse V2 cores for near-memory acceleration targeting deep learning recommendation models, while the Structera X focuses on memory expansion for capacity-intensive workloads like in-memory databases. The 5nm manufacturing process and support for four memory channels with inline LZ4 compression represent industry-leading specifications that should deliver superior performance and efficiency.

The IP licensing model for Structera adds another dimension to Marvell's strategy, allowing customers to embed this technology directly into custom silicon—a move that could significantly expand Marvell's footprint in workload-specific designs where memory bottlenecks are critical constraints. This positions Marvell as both a component supplier and an IP provider in the rapidly growing memory expansion market driven by AI workloads.

Proven Interoperability and Flexibility Drives Hyperscaler Deployment of Next-Generation Scalable Infrastructure

SANTA CLARA, Calif., Sept. 2, 2025 /PRNewswire/ -- Marvell Technology, Inc. (NASDAQ: MRVL), a leader in data infrastructure semiconductor solutions, today announced the Marvell^® Structera™ Compute Express Link^® (CXL^®) memory-expansion controllers and near memory compute accelerators have successfully completed interoperability testing with DDR4 and DDR5 memory solutions from industry leaders Micron Technology, Samsung Electronics, and SK hynix. This milestone follows the recent announcement "Successful Interoperability of Structera CXL Portfolio with AMD EPYC CPU and 5th Gen Intel Xeon Scalable Platforms," making Structera the only CXL 2.0 product family with completed interoperability testing across both leading CPU architectures and all three major memory suppliers.

As data-centric applications grow in complexity and memory plays a greater role in performance, interoperability is critical. Validation of Structera with DDR4 and DDR5 enables scalable system design, reduces integration risk, and streamlines qualification, while giving OEMs and cloud providers the flexibility to optimize system designs while maintaining supply chain flexibility.

To meet hyperscalers' demand for seamless integration across diverse memory and CPU technologies, Structera ensures compatibility and flexible configuration options that accelerate qualification and enable scalable deployment. A flexible business engagement model from Marvell enables innovative deployment strategies for Structera, allowing tailored product configurations that align with specific workload requirements and support both standard and custom deployment models.

To support diverse system architectures, Structera IP is available for integration into custom silicon designs. This allows customers to embed silicon-proven CXL technology from Marvell directly into their chips, unlocking new opportunities to optimize workload-specific performance, power efficiency, and system cost. The IP offering supports a broad range of integration models—from fully custom SoCs to tightly coupled accelerators—providing design flexibility while leveraging the mature CXL ecosystem and interoperability leadership developed by Marvell.

"As AI and high-performance computing workloads intensify, CXL will help dissolve bottlenecks for demanding workloads that can consume upwards of hundreds of terabytes of memory capacity," said Praveen Vaidyanathan, vice president and general manager of Cloud Memory Products at Micron. "Our collaboration with Marvell to validate Structera with Micron's memory technology is expected to deliver scalable, high-efficiency CXL infrastructure for the new frontier of AI." 

"CXL is reshaping how memory is deployed in data centers," said Jangseok Choi, vice president at Samsung Electronics. "Our work with Marvell ensures that customers can confidently deploy Structera with Samsung DDR memory for reliable, high-performance systems."

"Working with Marvell to validate Structera with SK hynix memory supports our shared goal of making memory expansion more accessible and flexible," said Uksong Kang, Head of Next Generation Product Planning and Enabling at SK hynix. "This gives customers the tools they need to build future-ready architectures with less friction and more choice." 

The Structera product line includes two CXL device families engineered to meet the diverse performance and scalability needs of next-generation cloud data centers. The Structera A CXL near-memory accelerators integrate 16 Arm^® Neoverse^® V2 cores and multiple memory channels with CXL to address high-bandwidth memory applications such as deep learning recommendation models (DLRM) and machine learning. The Structera X CXL memory-expansion controllers enable terabytes of memory to be added to general-purpose servers and address high-capacity memory applications such as in-memory databases. The Structera CXL device families are the industry's first to support four memory channels, integrate inline LZ4 compression and use 5nm manufacturing processes.
