Hot Chips 2026: Applying High Bandwidth Flash (HBF)

https://substackcdn.com/image/fetch/$s_!TXwa!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fa51c9bf3-0d5c-4fb9-9ccc-bc0915b15005_1901x1047.png
High Bandwidth Flash (HBF) is a new memory technology that could improve machine learning workloads by offering higher capacity and decent bandwidth, but it requires significant software changes. HBF's high capacity can alleviate DRAM shortages, but its low bandwidth makes it less suitable for applications with high compute throughput or memory access patterns.
