NVHBM: Can Custom HBM Change Who Builds the Memory Stack?

What happened

According to October 18 reporting from Seoul Economic Daily, NVIDIA has asked Samsung and SK (the article body is truncated at this point, so the full content of the request is not given). The report centers on NVIDIA's NVHBM, stating that NVHBM could change more than how memory connects to an AI accelerator; it could also change how the semiconductor industry divides responsibility for designing, manufacturing, and qualifying high-bandwidth memory (HBM). As of now this remains a reported request/proposal stage, with no information on implementation, approval, or taking effect; the source does not state the cause.
