High Bandwidth Flash Finds a Narrow Role Between NAND and HBM

At Hot Chips 2026, OXMIQ framed High Bandwidth Flash as a capacity-focused tier for AI systems. The proposed format combines stacked 3D NAND with UCIe links and aims to offer far more capacity than HBM at a comparable cost point. OXMIQ's modeling also shows lower aggregate bandwidth, so the economics worsen when throughput is the limiting factor. Availability for the fastest proposed grades has not been disclosed.
