SK Hynix bets on EUV to extend 6F² DRAM as CXMT pushes 4F²

SK Hynix plans to extend the life of its existing 6F² DRAM cell architecture using EUV lithography and process improvements. 4F² and 3D DRAM remain on its roadmap as China's CXMT advances its own 4F² work.

• SK Hynix keeps 6F² DRAM alive with EUV and process upgrades
• 4F² and 3D DRAM stay on SK Hynix's technology roadmap
• China's CXMT is pushing its own 4F² DRAM architecture
