SK Hynix Inc. will shutter its image sensor business as the South Korean memory giant doubles down on the development of premium artificial intelligence memory chips.
SK Hynix announced its decision to discontinue the image sensor business during an internal meeting with employees in its CMOS image sensor (CIS) division on Thursday.
“Shifting the capabilities we’ve built in the image sensor business to AI memory will enhance our position as a global leader in the AI-driven semiconductor era,” the company said in a statement.
Following the decision, the memory chip giant will reassign hundreds of CIS employees to its AI memory business.
The decision comes as SK Hynix positions itself at the forefront of the booming AI chip market, where demand for cutting-edge memory solutions is accelerating rapidly.
It is the global leader in high-bandwidth memory (HBM), a crucial component for AI applications, including AI servers and advanced computing systems.
As the lead HBM supplier to Nvidia Corp., SK Hynix plans to deliver 12-layer HBM4 chips, the most advanced AI chips available, to the world’s largest AI chip designer six months earlier than its initial schedule of early 2026.
TOO BIG TO CATCH UP
SK Hynix entered the image sensor market in 2007 and bolstered its presence after acquiring a Korean image sensor developer SiliconFile Technologies Inc. a year later.
CIS converts the light coming through the lens into a digital signal and displays it as an image. It is widely used in cameras for electronic devices, including smartphones, tablets, digital cameras and smart TVs, as well as security cameras and systems, medical applications and automobiles.
In 2019, SK Hynix opened a CIS-dedicated research and development center in Japan and launched its own image sensor brand, Black Pearl.
However, the highly competitive image sensor space, long dominated by Japan’s Sony Semiconductor Solutions Corporation (SSS) and its cross-town rival Samsung Electronics Co., has proven difficult to penetrate.
Sony led the market in 2024 with a 45% share and the runner-up, Samsung, with 19%, leaving SK Hynix with limited room for growth.
Struggles to secure major customers, coupled with mounting pressure to improve profitability, have prompted internal calls to scale back or abandon its CIS business entirely.
SK Hynix expects its expertise in logic semiconductor design and customized product development gained from its image sensor operations will help the company strengthen its AI memory chip development capabilities.
