Shares of SK Hynix Inc. (KS:000660) surged to an all-time high on Friday after the South Korean chipmaker announced the completion of its next-generation high-bandwidth memory, HBM4. The advanced chip, designed for artificial intelligence applications, is expected to significantly boost performance and efficiency for data-driven industries.
SK Hynix highlighted that HBM4 offers nearly double the bandwidth of its predecessor while improving power efficiency by over 40%. This leap is made possible through the integration of 2,048 input-output terminals, setting a new benchmark in memory innovation. The company confirmed that mass production preparations for HBM4 are complete, signaling strong momentum in the AI hardware market.
The new memory also achieved speeds above 10 gigabits per second, surpassing the 8 Gbps industry standard defined by JEDEC (Joint Electron Device Engineering Council). According to SK Hynix, this improvement could enhance AI service performance by up to 69% while cutting power costs—a critical factor for energy-intensive data centers.
Driven by this breakthrough, Seoul-listed shares of SK Hynix jumped nearly 6% to a record 326,000 won by 01:37 GMT. The stock has gained close to 20% this week, fueled by renewed optimism surrounding AI technology and rising demand for advanced semiconductors.
As AI adoption accelerates globally, HBM4 positions SK Hynix at the forefront of next-generation memory solutions. The company’s innovation not only strengthens its competitiveness against rivals but also addresses growing concerns over energy consumption in large-scale data operations.
With its record-setting performance and energy-saving capabilities, HBM4 is set to play a pivotal role in powering the future of artificial intelligence and data-driven services, further boosting SK Hynix’s position as a leader in the semiconductor industry.
