Samsung shares soar as company ships high-bandwidth memory chip samples globally Samsung launches 12-layer HBM4E AI memory chip samples, touting 16 Gbps speed and 48GB capacity, plans 32GB and 64GB versions, shares jump up to 6.51 percent By CNBCTV18.com After Samsung Electronics announced that it had started sending samples of its newest high-bandwidth memory chip to its clients worldwide, the company's stock shot up as much as 6.51%. According to a press release from the firm, Samsung's 12-layer HBM4E chip, which it called an industry first, can achieve speeds of up to 16 Gigabits per second "with improved energy efficiency and thermal performance". Advanced artificial intelligence systems utilise high-bandwidth memory chips, as those made by Samsung, SK Hynix, and Micron. They enable processors to process massive volumes of data rapidly, which is necessary for AI accelerators like Google's Ironwood Tensor Processing Unit and Nvidia's Rubin.
