ScaleFlux Unveils Next-Generation PCIe Gen 6 Controllers for AI and Cloud Infrastructure

At the Future of Memory and Storage (FMS) 2026, ScaleFlux is set to debut two advanced PCIe Gen 6 silicon solutions: the FC6116 PCIe Gen 6 NVMe SSD Controller and the MC600 PCIe Gen 6 CXL 3.2 Type 3 Memory Controller. These new products significantly expand ScaleFlux’s portfolio, delivering high-performance storage and memory controller technologies designed to meet the evolving needs of AI, hyperscale cloud, and enterprise infrastructure.

With a focus on higher bandwidth, lower power consumption, and enhanced scalability, ScaleFlux’s latest controllers are engineered to support the next wave of data-intensive applications. The company’s approach goes beyond silicon, offering a comprehensive turnkey solution that includes production-ready firmware, validated reference designs, and contract manufacturing partner support. This enables customers to accelerate development cycles, streamline qualification processes, and reduce time-to-market for new products.

FC6116 PCIe Gen 6 NVMe SSD Controller: Powering High-Performance Storage

The FC6116 stands as ScaleFlux’s flagship PCIe Gen 6 NVMe SSD controller, purpose-built for demanding AI, hyperscale, enterprise, and cloud storage environments. Supporting both PCIe Gen 6 x4 and dual-port 2x2 configurations, the FC6116 delivers:

  • Up to 28 GB/s sequential read throughput, fully utilizing the Gen 6 x4 interface
  • Up to 25 GB/s sequential write throughput
  • Up to 7 million 4 KB random read IOPS
  • Over 1 million sustained 4 KB random write IOPS
  • Active controller power consumption under 9 W

The controller is compatible with TLC, QLC, and SLC NAND, supporting capacities up to 256 TB and all major EDSFF form factors, including E1.S/L, E3.S/L, and U.2/3. Its turnkey Arm-based firmware platform accelerates product development and enables rapid customization for diverse customer requirements.

Designed for large-scale AI storage deployments, the FC6116 combines full PCIe Gen 6 bandwidth with outstanding power efficiency, resulting in higher bandwidth per watt, increased storage density, and reduced total cost of ownership.

Advanced Security and Reliability Features

The FC6116 integrates robust security and reliability features, including:

  • PCIe Integrity and Data Encryption (IDE)
  • OCP Caliptra 2.0 compliance
  • CNSA 2.0 post-quantum cryptography
  • S.A.F.E. security framework support
  • Firmware attestation
  • TCG Opal 2.0 support

For enterprise-class reliability, the controller offers full power-loss protection, end-to-end data path protection, advanced LDPC error correction, and compliance with the OCP Datacenter NVMe SSD Specification. Sampling for key customers is scheduled to begin in Q4 2026.

MC600 PCIe Gen 6 CXL 3.2 Type 3 Memory Controller: Enabling Efficient Memory Expansion

The MC600 PCIe Gen 6 CXL 3.2 Type 3 Memory Controller is engineered for next-generation memory expansion and pooling, delivering industry-leading power efficiency. Built on a PCIe Gen 6 physical layer and fully compliant with the CXL 3.2 specification, the MC600 enables high-capacity memory expansion while maintaining typical power consumption below 9 W in a PCIe Gen 6 x8 configuration. This efficiency allows hyperscale and cloud providers to scale memory capacity without increasing power or cooling demands.

The MC600 features:

  • Quad-channel DDR5 (40-bit) controller with 2DPC support
  • Dual-channel DDR4 (72-bit) controller with 2DPC support
  • Compatibility with RDIMM and UDIMM
  • Support for up to 2 TB of DDR5 memory

A key advantage of the MC600 is its native support for both DDR4 and DDR5 on a single controller, enabling customers to leverage existing DDR4 infrastructure while transitioning to advanced CXL memory architectures. This flexibility helps reduce capital expenditures and extends the lifecycle of deployed memory assets.

Comprehensive Security and Deployment Flexibility

The MC600 incorporates a comprehensive security architecture, including:

  • PCIe Integrity and Data Encryption (IDE)
  • OCP Caliptra 2.0 compliance
  • S.A.F.E. security framework support
  • Firmware attestation

Supporting PCIe add-in cards (AICs), EDSFF E3.S (1T and 2T), and custom form factors, the MC600 offers deployment flexibility across servers, AI systems, storage platforms, and edge computing environments. Sampling for key customers is expected to begin in Q4 2026.
