ScaleFlux bets smarter SSD controllers can break the AI memory bottleneck

ScaleFlux is pitching NAND flash as active memory for AI workloads rather than passive storage, pairing SSD and CXL memory controllers with firmware and a reference architecture. The company demonstrated over 200 flexible data placement streams and 7–10 drive writes per day on standard TLC NAND.

• GPU runs at 20–22 TB/s; DRAM is 37–40x slower, storage 800x slower
• ScaleFlux demonstrated 200+ flexible data placement streams on TLC NAND
• Achieved 7–10 drive writes per day on standard TLC NAND
• Controllers are NAND-agnostic, letting customers use any flash they can source
