Massive expansion: SK hynix to boost China production by 50%

Memory Giants: How SK hynix is Fueling the Future of Storage in China

In the high-stakes world of semiconductor manufacturing, demand for memory and storage is skyrocketing, driven primarily by the relentless appetite of artificial intelligence data centers. At the heart of this technological boom is SK hynix, a powerhouse that is strategically navigating global supply chains while making massive investments to secure its future in the memory market.

The company’s strategic maneuvers are particularly evident in its operations within China. Through its subsidiary, Solidigm, SK hynix is not just manufacturing chips; it is positioning itself to control a critical segment of the storage market. This ambition has led to significant planning regarding capacity expansion at its advanced fabrication facilities.

After a temporary pause in expansion—partially influenced by market fluctuations and evolving U.S. export controls—Solidigm is now pressing forward with renewed vigor. Reports indicate that investment in the Dalian facility, which serves as a crown jewel in SK hynix’s portfolio, has been resumed.

The focus is on maximizing production output to meet soaring demand. The second phase of the Dalian fab has been successfully completed, and preparations are underway to install production equipment as early as November. This expansion is designed to dramatically boost Solidigm’s capacity, aiming for a 50% increase in NAND production by 2027.

This expansion represents a substantial leap in manufacturing capability. By adding a new phase, the facility is projected to move from approximately 100,000 wafer starts per month (WSPM) to around 150,000 WSPM. This increased output is essential for fueling Solidigm’s ability to deliver high-capacity, premium solid-state drives that are highly sought after in the enterprise and data center sectors.

Crucially, these production upgrades align perfectly with technological advancements. Solidigm plans to utilize this enhanced capacity to begin manufacturing cutting-edge floating gate 3D QLC NAND memory, featuring over 200 active layers, at the Dalian campus in the second half of 2026. This goal is made possible by recently acquired advanced tool technologies.

The vision extends beyond domestic production. SK hynix is simultaneously weighing a strategic move to list some of Solidigm’s shares on NASDAQ. This potential offering could inject significant capital—estimated at up to $7 billion, based on unofficial reports—allowing the company to fund further capacity growth while retaining control over its valuable assets.

Ultimately, this dual strategy is about securing a leadership position in the evolving memory landscape. By combining physical expansion with strategic financial moves, SK hynix and Solidigm are positioning themselves not just to participate in the AI revolution, but to lead it, ensuring that the next generation of high-performance storage is built right at the core of global innovation.
