Updates with latest share moves, additional context
Investing.com-- Shares of SK Hynix Inc (KS:000660) climbed to a record high on Friday after the South Korean chipmaker said it had completed development of its next-generation high-bandwidth memory, known as HBM4, a key component for artificial intelligence applications.
The South Korean chipmaker said HBM4 will deliver roughly double the bandwidth of the previous generation and more than 40% improved power efficiency, aided by the adoption of 2,048 input-output terminals.
SK Hynix said it has completed preparations for mass production of HBM4.
It added that the product has achieved operating speeds above 10 gigabits per second, surpassing the 8 Gbps industry standard set by JEDEC (Joint Electron Device Engineering Council).
The company expects the new memory to improve AI service performance by as much as 69% while reducing power costs for data centres, where electricity demand is becoming a key concern.
Seoul-listed shares of the company jumped over 7% to hit a record high of 329,500 won by 06:18 GMT.
The stock has been on a tear in the past few sessions amid renewed AI optimism, and was set to jump nearly 20% for the week.
High Bandwidth Memory, or HBM, is a type of advanced DRAM that vertically stacks multiple chips to boost data transfer speeds while lowering power use. It has become a critical component in graphics processors and AI accelerators.
The company, a key supplier to Nvidia (NASDAQ:NVDA), overtook Samsung (KS:005930) in overall DRAM sales earlier this year, with the company commanding about 36% of the market in the first half compared with Samsung’s 33%, according to S&P Global.
