Apple is testing memory chips from ChangXin Memory Technologies (CXMT), a Chinese state-backed chipmaker on the Pentagon‘s blacklist. The testing applies only to devices sold in China. But the move signals Apple’s desperation to solve a global memory shortage that’s affecting production.

CEO Tim Cook has personally appealed to Trump administration officials, including Treasury Secretary Scott Bessent, to soften restrictions on Chinese chipmakers. Apple hasn’t committed to commercial use yet. But it’s negotiating.

Why Apple Needs Chinese Chips

The global DRAM shortage is real. Samsung, SK Hynix, and Micron—the three established players—can’t meet demand. CXMT has become the world’s fourth-largest DRAM producer. The Chinese company now accounts for 11% of global DRAM capacity. By 2028, that share is expected to reach 15%.

Apple’s supply chain operates on razor-thin margins. A shortage that slows production cascades through everything. Phones don’t get built on schedule. Revenue misses targets. Investors punish the stock. Solving the shortage is existential.

The Political Problem

CXMT is on the Pentagon blacklist. Trading with blacklisted entities violates U.S. policy. Apple buying CXMT chips complicates U.S.-China relations at a moment when tensions are already high.

But Apple’s argument is simple: if the company can’t get the chips it needs domestically, it’ll buy them internationally. That’s capitalism. Restricting that harms American companies more than it harms China.

Trump administration officials are listening. The political calculation is shifting. It’s hard to justify restricting supply chains when American companies are suffering.

The China-U.S. Chip War

CXMT itself is a geopolitical story. The company emerged from heavy government subsidies. It’s not a market player that competed its way here. It’s a strategic asset the Chinese government built intentionally.

U.S. policy has long been to slow China’s semiconductor independence. But market forces are overwhelming policy. CXMT exists. They make good chips. Companies need them. Restrictions only delay the inevitable.

What Commercial Use Would Mean

If Apple commits to CXMT chips commercially—not just in China, but globally—it signals a major shift in tech supply chains. Other companies would follow. The precedent that U.S. tech can’t buy from Chinese foundries would collapse.

For now, Apple is testing. That’s the safer move. It keeps options open without committing to something politically fraught. By August, we’ll know more about whether these tests proceed to commercial deployment.

Supply chains bend when necessity meets economics. Apple’s testing suggests both are pushing hard on the same direction.

FYI (keeping you in the loop)

What makes CXMT’s chips different from other producers?

CXMT uses similar manufacturing techniques to Samsung and SK Hynix but with lower production costs due to government subsidies. The quality is comparable. The availability is better. From a pure engineering standpoint, CXMT chips work fine in Apple devices.
