Samsung Shares Surge 6.5% After Shipping HBM4E Samples
Samsung shares surged as much as 6.51% after the company began shipping samples of its industry-first 12-layer HBM4E AI memory chip globally. The development advances Samsung's push to compete with SK Hynix in high-bandwidth memory for AI accelerators from Nvidia and Google.

The chipmaker's 12-layer HBM4E chip, which it described as an industry first, can reach speeds of up to 16 Gigabits-per-second with improved energy efficiency and thermal performance, the company said in a press release. Samsung also noted that HBM4E was faster than its previous HBM4 products.
High Bandwidth Memory chips, such as those produced by Samsung, SK Hynix and Micron are used in advanced artificial intelligence systems.
High Bandwidth Memory chips, such as those produced by Samsung, SK Hynix and Micron are used in advanced artificial intelligence systems. They help processors handle large amounts of data quickly, required by AI accelerators such as Nvidia's Rubin and Google's Ironwood Tensor Processing Unit.
Samsung's 12-layer HBM4E, which stacks Dynamic Random-Access Memory vertically, has a 48-gigabyte capacity, representing more than a 30% increase compared with the previous generation, the company said. The South Korean chipmaker added that there are plans to expand the lineup to include an 8-layer 32GB and a 16-layer 64GB configuration, depending on customer requirements.
"Through our advanced manufacturing capabilities and preemptive infrastructure investments, we will continue to drive the growth of the global AI memory market," said Sang Joon Hwang, executive vice president and head of memory development at Samsung Electronics.
Samsung is pushing to gain ground in next-generation AI memory.
The news comes after Samsung began shipping HBM4 chips to customers in February, as it seeks to narrow the gap with SK Hynix and strengthen its position in the next-generation AI memory market. Samsung is pushing to gain ground in next-generation AI memory.
