As SK hynix and Samsung are releasing their financial results on July 25^th and July 31st, respectively, their progress on HBM3 and HBM3e have also been brought into spotlight. Earlier this week, Samsung is said to eventually passed NVIDIA’s qualification tests for its HBM3 chips. While the Big Three in the memory sector are now almost on the same page, the war between HBM3/ HBM3e is expected to intensify in the second half of 2024.

Samsung Takes a Big Leap

According to reports from Reuters and the Korea Economic Daily, Samsung’s HBM3 chips have been cleared by NVIDIA, which will initially be used exclusively in the AI giant’s H20, a less advanced GPU tailored for the Chinese market. Citing sources familiar with the matter, the reports note that Samsung may begin supplying HBM3 to NVIDIA as early as August.

However, as the U.S. is reportedly considering to implement new trade sanctions on China in October, looking to further limit China’s access to advanced AI chip technology, NVIDIA’s HGX-H20 AI GPUs might face a sales ban. Whether and to what extent would Samsung’s momentum be impacted remains to be seen.

SK hynix Eyes HBM3e to Account > 50% of Total HBM Shipments

SK hynix, as the current HBM market leader, has expressed its optimism in securing the throne on HBM3. According to a report by Business Korea, citing Kim Woo-hyun, vice president and chief financial officer of SK hynix, the company significantly expanded its HBM3e shipments in the second quarter as demand surged.

Moreover, SK hynix reportedly expects its HBM3e shipments to surpass those of HBM3 in the third quarter, with HBM3e accounting for more than half of the total HBM shipments in 2024.

SK hynix started mass production of the 8-layer HBM3e for NVIDIA in March, and now it is also confident about the progress on the 12-layer HBM3e. According to Business Korea, the company expects to begin supplying 12-layer HBM3e products to its customers in the fourth quarter. In addition, it projects the supply of 12-layer products to surpass that of 8-layer products in the first half of 2025.

Micron Expands at Full Throttle

Micron, on the other hand, has reportedly started mass production of 8-layer HBM3e in February, according to a previous report from Korea Joongang Daily. The company is also reportedly planning to complete preparations for mass production of 12-layer HBM3e in the second half and supply it to major customers like NVIDIA in 2025.

Targeting to achieve a 20% to 25% market share in HBM by 2025, Micron is said to be building a pilot production line for HBM in the U.S. and is considering producing HBM in Malaysia for the first time to capture more demand from the AI boom, a report by Nikkei notes. Micron’s largest HBM production facility is located in Taichung, Taiwan, where expansion efforts are also underway.

Earlier in May, a report from a Japanese media outlet The Daily Industrial News also indicated that Micron planned to build a new DRAM plant in Hiroshima, with construction scheduled to begin in early 2026 and aiming for completion of plant buildings and first tool-in by the end of 2027.

TrendForce’s latest report on the memory industry reveals that DRAM revenue is expected to see significant increases of 75% in 2024, driven by the rise of high-value products like HBM. As the market keeps booming, would Samsung come from behind and take the lead in the HBM3e battle ground? Or would SK hynix defend its throne? The progress of 12-layer HBM3e may be a key factor to watch.
