SK Hynix chipping away at AI memory wall from several angles
SK Hynix is expanding its AI memory business through investments in fabs in China, Japan, Korea, and the USA, and fundraising for its subsidiary Solidigm. The company is also developing high-bandwidth flash and co-packaged optics to meet AI demand. Solidigm, valued at $36 billion, aims to raise $7.2 billion, with potential investors including Techbridge Investment and Mubadala.
