The vast majority of High Bandwidth Memory (HBM) new stories—so far, in 2025—have involved or alluded to new-generation SK hynix and Micron products. As mentioned in recently published Samsung Electronics Q1 financial papers, company engineers are still working on "upcoming enhanced HBM3E products." Late last month, a neighbor/main rival publicly showcased their groundbreaking HBM4 memory solution—indicating a market leading development position. Samsung has officially roadmapped a futuristic "sixth-generation" HBM4 technology, but their immediate focus seems to be a targeted sales expansion of incoming "enhanced HBM3E 12H" products. Previously, the firm's Memory Business has lost HBM3 ground—within AI GPU/accelerator market segments—to key competitors.

Industry insiders believe that company leadership will attempt to regain lost market shares in a post-2025 world. As reported by South Korean news outlets, Kim Jae-joon (VP of Samsung's memory department) stated—during a recent earnings call, with analysts—that his team is: "already collaborating with multiple customers on custom versions based on both HBM4 and the enhanced HBM4E." The initiation of commercial shipments is anticipated at some point in 2026, hinging on mass production starting by the second half of this year. The boss notified listeners about development "running on schedule." A Hankyung article alleges that Samsung HBM4 evaluation samples have been sent out to "NVIDIA, Broadcom, and Google." Wccftech posits a positive early outlook: "Samsung will use its own 4 nm process from the foundry division and utilize the 10 nm 6th-generation 1c DRAM, which is known as one of the highest-end in the market. On paper, (their) HBM4 solution will be on par with competing models (from SK hynix), but we will have to wait and see."
