Samsung Electronics plans to begin production of its next-generation high-bandwidth memory chips, known as HBM4, next month and supply them to Nvidia, a person familiar with the matter told Reuters.
The move marks a key step in Samsung’s efforts to close the gap with local rival SK Hynix, which has emerged as the primary supplier of advanced memory used in Nvidia’s AI accelerators. Earlier supply delays had weighed on Samsung’s earnings and share price last year.
Samsung shares rose 2.2% in morning trade, while SK Hynix shares fell 2.9%. The source declined to disclose shipment volumes. Samsung declined to comment, and Nvidia was not immediately available for comment.
South Korean newspaper Korea Economic Daily reported that Samsung recently passed HBM4 qualification tests for Nvidia and AMD, and is set to begin shipments to Nvidia next month, citing industry sources.
SK Hynix said in October it had completed supply talks with major customers for next year and plans to deploy silicon wafers at its new M15X fab in Cheongju starting next month. It has not confirmed whether HBM4 will be part of the initial output.
Both Samsung and SK Hynix are due to report fourth-quarter earnings later this week, when further details on HBM4 orders are expected. Nvidia CEO Jensen Huang has said the company’s next-generation Vera Rubin AI platform is already in full production and will be paired with HBM4 chips later this year.
