High-end AI accelerators such as the NVIDIA H100 integrate HBM3
Changxin Memory Technologies (CXMT) announced the launch of risk mass production of HBM3 hundred-million-level memory.
CXMT (Changxin Memory Technologies) has begun small-volume production of HBM3 high-bandwidth memory.
A high-end AI training card may require 80 GB or even more HBM3 memory.
The HBM3 used in NVIDIA's H100 provides over 3 TB/s of bandwidth, and HBM is primarily supplied by three manufacturers: SK Hynix, Samsung, and Micron.
HBM通过TSV（硅通孔）垂直互连多层DRAM，HBM3为8-12层，TSV是直径约5-10微米的铜柱
