Key Highlights
- Google introduced TurboQuant, a groundbreaking algorithm capable of cutting AI memory needs by up to six-fold
- Samsung shares declined 4.8% while SK Hynix plummeted 6.23% following the announcement
- American memory chip manufacturers Micron, SanDisk, and Western Digital experienced losses ranging from 1.6% to 3.5%
- Market analysts interpret the downturn as temporary profit-taking rather than a fundamental shift in demand trajectory
- TurboQuant’s official unveiling is scheduled for the ICLR 2026 conference in April
Shares of South Korean memory chip giants Samsung and SK Hynix experienced significant declines Thursday in response to Google researchers announcing TurboQuant, an innovative AI memory compression technology.
Samsung’s stock retreated 4.8% while SK Hynix saw a steeper decline of 6.23% during trading on the Korea Exchange. The two companies ranked among the heaviest weights pulling down the KOSPI index, which lost as much as 3% throughout the session.
The electrical and electronics sector benchmark similarly retreated 4.76%, settling at 3,592.22 points.
The downturn mirrored previous declines among American memory chip manufacturers. Micron Technology shed 3.40%, while SanDisk declined 3.50% and Western Digital fell 1.63% during New York Stock Exchange trading.
Earlier in the week, Google researchers announced TurboQuant, describing an algorithm with the capability to enable AI systems to process up to six times greater capacity while utilizing identical memory resources.
According to Google, the innovation also enhances vector search functionalities that drive leading search platforms.
Market participants expressed apprehension that diminished memory requirements might curtail demand for the sophisticated memory components that Samsung and SK Hynix manufacture for data center applications.
Both manufacturers have experienced substantial gains from AI-fueled demand. This demand trend had been anticipated to create memory chip supply constraints in recent periods and powered significant stock appreciation for both corporations.
Market Experts Challenge Negative Interpretation
The majority of financial analysts characterize the decline as temporary profit-taking. Industry watchers contend the innovation may actually bolster memory demand in the longer term.
Surim Lee, an equity research analyst at DS Investment & Securities, explained that technologies designed to reduce memory consumption historically expand aggregate demand rather than diminish it. He emphasized that TurboQuant’s development stems from memory constraints in AI infrastructure having already reached critical thresholds.
Lee further explained that efficiency improvements generate a positive cycle where reduced costs drive increased utilization and reinvestment, rather than decreased overall demand.
Han Ji-young of Kiwoom Securities observed that as AI systems become increasingly efficient and capable, paradoxically, total AI demand could accelerate.
Han additionally suggested the pronounced stock decline probably reflected investor exhaustion following the early-year memory price surge, with TurboQuant news providing justification for profit realization.
Past Trends Reinforce Positive Outlook
Throughout history, innovations that enhance resource efficiency have frequently catalyzed accelerated industry expansion and elevated aggregate demand, contrary to reduction.
Heo Jae-hwan of Eugene Investment & Securities indicated that server and semiconductor segments connected to AI, where supply constraints already exist, will likely demonstrate greater resilience compared to alternative industries.
Google confirmed it will officially present TurboQuant during the ICLR 2026 conference scheduled for April.
Samsung and SK Hynix concluded trading at 1,801,000 won and 9,330,000 won respectively on the Korea Exchange on March 26.
