Samsung is working on HBM5 with the possibility of using even 2‑nm crystals

New Steps by Nvidia and Samsung in Developing HBM Memory

This month, Nvidia’s leadership confirmed its confidence in the quality of Samsung Electronics’ HBM4 memory: founder Jensen Huang personally remarked on a demo wafer with HBM4 chips that the memory is “amazing.” Meanwhile, Samsung is already working on the next versions—HBM5 and HBM5E.

What Business Korea reported
* Samsung’s HBM5

* The base crystal (memory stack) will be manufactured using 2 nm technology.

* DRAM crystals in the stack use the sixth generation of the 10 nm process, referred to as “1c.”

* Samsung’s HBM5E

* Based on the same 2 nm crystal.

* The DRAM portion will be fabricated using a newer version of the 10 nm process—“1d.”

Thus, Samsung combines the latest and proven technologies to reduce risks in HBM production.

Collaboration with Nvidia
* Groq 3 – specialized processors that Samsung will now produce on contract capacity using the 4 nm process.

* Samsung’s division head Han Jin‑man emphasized: “4 nm cannot be considered mediocre.”

* Nvidia has long collaborated with Samsung on LPU chips (2023) and chose its 4 nm process for Groq 3.

* Mass production is planned for the end of Q3/early Q4 this year, with significant demand expected from next year.

GTC 2026 Event
At GTC 2026 in California, Nvidia announced a partnership and showcased HBM4, HBM5, and Groq 3 chips.

* Huang signed an autograph on a wafer with Groq 3, calling them “super‑fast.”

* Samsung and SK hynix representatives were also present—underscoring the importance of Korean suppliers to Nvidia.

Key Takeaways

1. Reliable partner – Samsung is successfully developing HBM4, and now HBM5/EBM5 using 2 nm technology for base crystals and proven 10 nm processes for DRAM parts.

2. Technological breakthrough – moving to 2 nm boosts performance and reduces manufacturing errors.

3. Compatibility guarantee – existing collaboration with Nvidia (Groq) confirms that Samsung can supply chips meeting required standards.

Thus, Nvidia sees Samsung as a reliable partner for further development of high‑performance memory and specialized processors.
