In the High Bandwidth Memory portfolio
Shinebolt is Samsung's HBM3E generation, offered in 8-high 24 GB and 12-high 36 GB stacks at pin speeds up to 9.8 Gbps — over 1.25 TB/s per stack at the top bin. Samsung's NCF-based thermal-compression bonding manages warpage and heat across the taller stack.
As a second qualified source for HBM3E, Shinebolt matters to accelerator programs balancing supply risk across vendors. Samsung pairs the product with its own 2.5D packaging services for customers seeking a combined memory-and-interposer supply chain.
