Memory Report — 2026-07-03

Samsung is closing the HBM gap fast, with fresh internal testing showing its seventh-generation HBM4E clearing reliability yields above 70 percent, a milestone that sharpens a three-way race for the next allocation cycle even as SK Hynix and Micron press their leads.

Samsung Electronics is moving closer to commercializing HBM4E, its seventh-generation high-bandwidth memory, after internal testing showed reliability yields above 70 percent, strengthening its bid to gain ground in the AI memory market. That matters because Samsung's HBM problem was never installed capacity, it was yield and qualification, and clearing that bar is the prerequisite for winning back share it ceded on HBM4. Rivals are not standing still. SK Hynix has delivered 12-layer HBM4E samples to key clients, with development chief Ahn Hyun saying the company has laid the foundation to strengthen its AI leadership with HBM4E and is working closely with partners toward mass production. Those 12-layer HBM4E modules process data at up to 16 gigabits per second per pin and are 20 percent more power efficient than earlier versions.

The bigger capital story landed alongside it. SK Hynix unveiled a long-term investment plan totaling 1,100 trillion won, allocating 600 trillion won to the Yongin semiconductor cluster, 100 trillion won to its Cheongju base, and 400 trillion won to a new cluster in South Korea's southwest region. The company will accelerate completion of the Yongin cluster from an original target of 2045 to 2033, pulling the project forward by 12 years, with the fourth and final fab scheduled for completion by 2033. This sits inside a national push: Samsung and SK Hynix will invest 800 trillion won, roughly 518 billion dollars, with suppliers to build two new fabrication sites each in the southwest, alongside a further 81 trillion won for a chip packaging cluster in the Chungcheong area. The rationale is blunt. SK Group Chairman Chey Tae-won said the memory market already has an extreme supply shortage, and that the shortage will become even more severe.

To bankroll it, SK Hynix plans to list American depositary receipts on the Nasdaq Global Select Exchange on July 10, aiming to raise 45.45 trillion won, about 29 billion dollars, well above the roughly 10 billion dollars previously floated by Korean media. SK Hynix has meanwhile overtaken Samsung this week to become South Korea's most valuable listed company, a position Samsung had held for 26 years. On pricing, the tape stays firm: TrendForce's June 30 contract-price update shows DRAM contract prices continuing to rise, driven by tight supply and expectations of negative production growth, with manufacturers still raising quotes.

Watch July 10 for the Nasdaq debut, which will test how much AI-memory premium public markets are willing to price into a pure-play memory maker at the top of a supercycle.
