SEOUL (Reuters) – SK Hynix stated on Friday it has accomplished its inside certification course of for subsequent technology high-bandwidth reminiscence 4(HBM4) chips and established a manufacturing system for patrons because it seeks to retain a lead over rivals.
In March, the South Korean chipmaker, a key provider to AI big Nvidia, stated it had shipped its HBM4 12-layer chip samples to clients, including that the corporate goals to finish preparations for mass manufacturing of 12-layer HBM4 merchandise throughout the second half of this yr.
HBM – a kind of dynamic random entry reminiscence or DRAM normal first produced in 2013 – entails stacking chips vertically to avoid wasting area and cut back energy consumption, serving to to course of the massive volumes of information generated by advanced AI functions.
Kim Sunwoo, a senior analyst at Meritz Securities, projected that SK Hynix’s HBM market share will stay within the low 60% vary in 2026, in comparison with this yr’s 66% market share, supported by early HBM4 provide to key clients and the ensuing first-mover benefit.

Samsung stated in July that it had offered samples of its HBM4 chips to clients, with a plan to produce them subsequent yr.
An SK Hynix govt informed Reuters in an interview final month that due to technological adjustments in how SK Hynix and rivals corresponding to Micron and Samsung construct next-generation HBM4, their merchandise embrace a customer-specific logic die, or “base die”, that helps handle the reminiscence.
