Nvidia and SK hynix have signed a multi-year co-development agreement for next-generation memory technologies, addressing the AI industry's toughest bottleneck. The deal covers HBM4 for Vera Rubin systems and extends to semiconductor research, with SK hynix securing an estimated 60-70% of HBM4 volume. Jensen Huang announced the partnership during his South Korea tour, where he also unveiled RTX Spark and met with major Korean tech firms.

Nvidia and SK hynix Lock in Multi-Year Memory Partnership

Nvidia and SK hynix have formalized a multi-year agreement that goes far beyond a standard supply contract, establishing a co-development framework for next-generation memory technologies that will power the next wave of AI infrastructure

HBM4 Supply and Vera Rubin Dominance

The agreement positions SK hynix as the dominant memory supplier for Nvidia's Vera Rubin platform, with industry analysts estimating the South Korean chipmaker holds roughly 60% to 70% of HBM4 volume allocated to these next-generation AI systems

3

. Samsung supplies approximately 25% to 30%, while Micron provides the remainder. Vera Rubin, built around clusters of Vera central processing units and Rubin graphics cores paired with terabytes of HBM4 in each server system, reportedly delivers 3.5 times the training performance and five times the inference performance of its Blackwell predecessor

3

. Shipments are expected to begin in Q3 2026, involving over 350 supply chain partners across 30 countries. The initial cooperation covers memory destined for Nvidia Vera Rubin AI systems, including HBM4, LPDDR5X, and 3D NAND, as well as standalone Vera processors, RTX Spark-powered personal computers, and Jetson Thor robotic computing systems

Addressing Extended Development Cycles for AI Factories

The multi-year agreement tackles the increasingly long lead times and massive capital expenditures required for advanced memory production by coordinating roadmaps over multiple years

1

. Nvidia gains greater visibility into future memory availability for what it calls "AI factories"—the large-scale AI data centers used for training and inference—while SK hynix secures guaranteed demand for its output

. The South Korean memory chipmaker said the deal would help maintain a stable supply of memory despite advanced memory's long development cycles and enable entry into new AI fields such as personal AI and physical AI

2

. HBM capacity is projected to remain tight through at least 2028, with some forecasts extending constraints to 2030 in what analysts at TrendForce have described as a "memory supercycle"

Jensen Huang's South Korea Tour Signals Broader Strategy

The SK hynix announcement was part of a broader series of deals during Huang's visit to South Korea, where he met with executives from Hyundai, LG, SK, Samsung, and Naver. Huang told reporters he sees robotics as the next major sector in South Korea, emphasizing partnerships with the country's manufacturing firms in robotics and AI. Nvidia also announced that SK Telecom will build a new gigawatt-scale AI cloud powered by Nvidia chips, with the first data center coming online early next year, while Naver will use Nvidia's AI models to expand its data center capacity
