SK Hynix broke ground on 27 August on a $4 billion plant in West Lafayette, Indiana, that will package high bandwidth memory, the stacked DRAM that sits next to AI accelerators and that has been in short supply for more than a year. The site covers 133.5 acres. Indiana Governor Mike Braun and Senator Todd Young attended the ceremony, which Bloomberg and CNBC covered.
The plant handles packaging rather than wafer fabrication, so the memory chips themselves will still be made in South Korea and shipped over for final assembly. Chief executive Kwak Noh-Jung said the facility would make Indiana a key American base for the technology by 2030. The cleanroom is scheduled to open in October 2028, with mass production of next generation memory in the second half of 2029, and eventual employment of about 1,000 people.
SK Hynix first announced the Indiana site in April 2024, then costed at $3.87 billion. Breaking ground more than two years later, into a market where the memory is sold out well into next year, is a reminder of how little a new plant does for a shortage on any near term view. The company leads the high bandwidth memory market and says it is spending heavily to keep that position.
The distance between the ceremony and the first packaged part is roughly three years, and the demand it is meant to serve is a 2029 forecast. Whether AI chip volumes then still need this output, or whether the cycle has turned by the time the cleanroom opens, is the figure nobody at the podium offered.
