ICHEON, South Korea, May 2 (Reuters) - South Korea's SK

Hynix said on Thursday its high-bandwidth memory

(HBM) chips used in AI chipsets are almost sold out for 2025,

after their 2024 chips were fully booked.

Chief Executive Officer Kwak Noh-Jung said the Nvidia ( NVDA )

supplier and the world's second-largest memory chipmaker will

begin sending samples of the latest version of HBM chips, called

12-layer HBM3E, in May and begin mass producing them in the

third-quarter.

Kwak said its HBM products this year had already sold out,

while 2025 HBM volumes were almost sold out amid a rapid

expansion of AI technology into a wider range of on-device

applications such as smartphones, PCs, and automobiles.
