SK Hynix, one of the world's largest makers of memory chips, is hitting the U.S. stock market at a time when demand for its chips is outpacing its ability to make them thanks to the frenzy over artificial intelligence.

The company is already one of the largest in South Korea, along with Samsung Electronics, and is traded publicly on Seoul's Kospi index.

Even with a recent pullback, the Kospi is up 77% so far this year and SK Hynix shares have more than tripled.
