SK hynix approves $38B+ funding in two new reminiscence fabs

The board of SK hynix Inc., a serious knowledge heart reminiscence provider, at the moment accredited the development of two new fabs.

The initiative will value 54 trillion South Korean received, or about $38.3 billion. It’s a part of a broader $430 billion funding plan designed to broaden SK hynix’s manufacturing capability. That initiative, in flip, is itself a element of a multibillion-dollar push by the South Korean authorities to develop the native chip sector. The latter venture additionally consists of SK hynix rival Samsung Electronics Co.

SK hynix’s newly introduced building initiative will see it construct a $25 billion fab referred to as Yongin Y2. It’s the second of 4 chip factories that the corporate plans to construct on the Yongin Semiconductor Cluster, a producing campus about 20 miles south of Seoul. The primary fab within the sequence is anticipated to open its doorways subsequent February.

SK hynix plans to interrupt floor on Yongin Y2 in July 2027. The ability’s first cleanroom, a manufacturing facility part that accommodates chipmaking gear, is scheduled to return on-line in June 2029. The manufacturing facility could have 279 acres of flooring area as soon as building is full. 

Yongin Y2 will likely be devoted solely to DRAM manufacturing. SK hynix will use the fab to make, amongst different merchandise, HBM reminiscence. That’s the high-speed RAM utilized by graphics playing cards to retailer synthetic intelligence fashions and their knowledge.

SK hynix is the world’s largest HBM producer. An HBM chip contains a number of layers of RAM stacked atop each other, an association that makes it doable to maneuver knowledge to and from the hooked up AI chip at excessive pace. 

SK hynix debuted its most superior HBM gadget, a 12-layer chip, final September. It’s primarily based on a brand new model of the expertise referred to as HBM4. The usual offers greater than twice the bandwidth of the reminiscence that  powers at the moment’s graphics playing cards.

The second new fab that SK hynix plans to open will make NAND flash. It will likely be constructed on a campus that already hosts three of the corporate’s chip factories. Based on SK hynix, the prevailing energy and water infrastructure on the positioning will pace up building. The corporate expects to open the fab’s first cleanroom in December 2028.

Earlier this 12 months, SK hynix and companion Sandisk launched a brand new NAND flash expertise referred to as HBF. It stacks NAND flash circuits atop each other in a way just like HBM. Based on the businesses, the expertise can match the efficiency of HBM whereas offering as much as 16 instances extra capability.

Samsung, SK hynix’s prime rival within the reminiscence market, can be creating vertical reminiscence applied sciences.

As we speak, NAND and HBM modules are positioned subsequent to the logic circuits of the host chip. On Wednesday, Samsung debuted two new applied sciences that make it doable to stack NAND and HBM reminiscence instantly atop logic circuits. That association shortens the space between parts, which permits knowledge to journey quicker between them. The outcome is a rise in processing speeds.

Samsung estimates that its stackable HBM expertise will likely be eight instances quicker than HBM5, an upcoming model of HBM set to launch in direction of the top of the last decade. The corporate additionally expects a tenfold improve in reminiscence density, a measure of a RAM chip’s capability. Samsung will give clients the choice to additional optimize the expertise by including in customized interconnect parts.
