SK Hynix Shifts Strategy to Utilize TSMC 3nm Process for Seventh Generation HBM4E Memory Logic Die Targeting Nvidia Vera Rubin Ultra AI Chips
The memory market is reaching a fever pitch in 2026. It appears that SK Hynix is making a very expensive and very calculated bet on the future of high bandwidth memory. Recent whispers from the industry suggest the company is looking to utilize the 3nm process from TSMC for the logic die of its seventh generation HBM4E. This is a significant move. The logic die acts as the brain for the memory stack. By moving to such a fine process SK Hynix likely hopes to claw back the performance crown from Samsung Electronics.
In the previous HBM4 cycle SK Hynix seemed to prioritize a safe and proven path. They used a 12nm logic die which focused on stability. However the landscape has changed. Samsung pushed ahead with a 4nm logic die and 10nm class DRAM which forced a change in strategy. Now for the HBM4E generation SK Hynix is expected to pair 1c DRAM with that cutting edge 3nm logic. This might suggest they are tired of being told their tech lags behind in pure speed even if they still hold the volume lead with Nvidia.
Technical Specifications for Seventh Generation HBM4E
- Memory Generation HBM4E seventh generation
- Logic Die Tech TSMC 3nm process
- DRAM Tech 10nm class 6th generation 1c DRAM
- Target Hardware Nvidia Vera Rubin Ultra AI chips
The timing is critical. Samsung recently made a big scene at GTC 2026 by showing off their own HBM4E progress. This likely put some pressure on the leadership at SK Hynix. The goal now is to supply the most powerful memory for the Vera Rubin Ultra series from Nvidia. It is not just about one customer either. Many observers point out that Google and AMD are also lining up for this level of bandwidth. A 3nm logic die could potentially reduce the distance electrons travel and save a massive amount of power. In a world where AI data centers are starving for electricity these small efficiency gains are worth billions.
There is also the matter of custom memory. Some officials in the semiconductor world think that customers might want different options like 12nm for cheaper builds. Even so the 3nm process will almost certainly be the primary choice for the high end of the market. It seems SK Hynix is done playing it safe. They want to dominate both the volume and the performance charts this time around. We will have to see if this bold move pays off when mass production really ramps up later this year.
