South Korean memory chipmaker SK Hynix<\/a> said Friday that it was ready for mass producing its next-generation high-bandwidth memory chips, staying ahead of rivals, and sending the company’s stock soaring.\u00a0<\/p>\n HBM is a type of memory that is used in chipsets for artificial-intelligence computing, including in chips from\u00a0global AI giant Nvidia \u2014 a major client of SK Hynix.\u00a0<\/p>\n SK Hynix said earlier this year <\/a>that it had shipped samples of its HBM4 chips to customers, as it sought to beat competitors including Samsung Electronics and Micron Technologies.<\/p>\n According to its announcement<\/a> Friday, the company has finished its internal validation and quality assurance process for HBM4 and is ready to manufacture those at scale.<\/p>\n “Completion of HBM4 development will be a new milestone for the industry,” Joohwan Cho, head of HBM development at SK Hynix, said.<\/p>\n HBM4 is the sixth generation of HBM technology \u2014 a type of Dynamic Random Access Memory, or DRAM. DRAM can be found in personal computers, workstations and servers and is used to store data and program code.<\/p>\n SK Hynix’s latest HBM4 product has doubled bandwidth and increased power efficiency by 40% compared to the previous generation, according to the company.\u00a0\u00a0<\/p>\n Notably, HBM4 is expected to be the main AI memory chip needed for Nvidia’s next-generation Rubin architecture \u2014 a more powerful AI chip for global data centers \u2014 said Dan Nystedt, vice-president at TriOrient, an Asia-based private investment firm with a focus on semiconductors.<\/p>\n “SK Hynix is a key supplier for Nvidia, and the announcement shows it remains far ahead\u00a0of\u00a0rivals,” he said.<\/p>\n Samsung Electronics and Micron have struggled to catch up to SK Hynix in HBM, as it builds on its segment leadership and benefits from being Nvidia’s main HBM supplier.\u00a0<\/p>\n Micron has also shipped samples<\/a> of its HBM4 products to customers, while Samsung has reportedly <\/a>been working to get its HBM4 chips certified by Nvidia.\u00a0However, analysts expect<\/a> SK Hynix’s dominance to persist into next year.<\/p>\n This company’s shares rose more than 7% Friday to hit their highest since 2000, following its chip announcement, bringing year-to-date to nearly 90%.\u00a0Shares of Samsung Electronics and Micron have risen over 40% and nearly 80% in 2025, respectively.<\/p>\n SK Hynix posted record operating profit and revenue for its June-quarter, thanks to strong HBM demand, which accounted for 77% of its overall revenues.<\/p>\n The company expects to double HBM sales for the full year compared to 2024, and for demand from AI to continue to grow into 2026.<\/p>\n","protected":false},"excerpt":{"rendered":"A man walks past a logo of SK Hynix at the lobby of the company’s Bundang office in…\n","protected":false},"author":2,"featured_media":11213,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[354,114,357,85,46,12108,125],"class_list":{"0":"post-11212","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-business","8":"tag-breaking-news-technology","9":"tag-business","10":"tag-business-news","11":"tag-il","12":"tag-israel","13":"tag-sk-hynix-inc","14":"tag-technology"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/11212","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=11212"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/11212\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/11213"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=11212"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=11212"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=11212"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
