Rival memory giants share the exhibition floor

SEDEX, organized by the Korea Electronics Industries Association, is widely described as the country's largest semiconductor-focused exhibition. This year's edition will place the two Korean memory heavyweights in direct competition for visitor attention, as both seek to highlight their leadership in HBM, the high-value memory at the center of the AI boom.

SK hynix has publicly announced its participation in SEDEX 2025, promoting its presence under a theme centered on building the future of AI with memory semiconductors.

Next-generation HBM in the spotlight

According to the claim, both Samsung Electronics and SK hynix plan to unveil next-generation HBM technology at the show. SK hynix's participation and its AI memory-focused exhibition concept are confirmed by the company's own announcements. Details of Samsung Electronics' exact exhibition program, including whether it will formally "unveil" specific next-generation HBM products or technologies at the event, remain not fully confirmed.

Similarly, while SEDEX is broadly recognized as a major domestic semiconductor exhibition, characterizing it as the singular "largest in Korea" involves some degree of promotional framing rather than a strict, unique designation.

AI memory race continues

The face-off at SEDEX underscores the intensifying competition between Samsung Electronics and SK hynix in AI memory, a segment that has become the key growth driver for the memory industry. Both companies have staked their strategies on supplying HBM to global AI accelerator customers, and the exhibition offers a stage to showcase their technological credentials to domestic and international visitors.

The claim that the two companies will clash at this month's exhibition over next-generation HBM technology is largely accurate, though some elements — the certainty of the technology unveilings and the "largest in Korea" designation — are somewhat exaggerated. Verdict: Mostly True
