SK Hynix moves AI data centers from processor-centric to memory-centric design
What happened
SK Hynix presented the Memory-Centric AI Rack System (MARS) at the Open Compute Project (OCP) Global Summit. The architecture separates memory from individual servers and pools it at the rack level over Compute Express Link (CXL) fabrics. According to the company, this addresses the capacity and cost limits that are constraining the growth of large AI models. The source only states that the architecture was presented at the summit along with the company's claim; it does not state any implementation, mass production or deployment status, and no specific date is given.
