Samsung is reported to be planning to use TSMC’s 3nm process to produce basic chips for Nvidia’s next-generation customized high-bandwidth memory (HBM). Nvidia has asked Samsung, SK Hynix and Micron to uniformly use TSMC's 3nm process to manufacture basic chips to promote product standardization. 8. Musk said that next year he will give one share of his SpaceX shares to every American child. "This will be the first of many actions," he added. 9.
