SK hynix has developed its first DDR5 DRAM-based CXL (Compute Express Link) memory samples and strengthened its presence in next-generation memory solutions market. The form factor of the sample is EDSFF (Enterprise & Data Center Standard Form Factor) E3.S and it supports PCIe 5.0 x8 Lane, uses DDR5 standard DRAM and is equipped with CXL controllers. CXL, which is based on PCIe (Peripheral Component Interconnect Express), is a new standardized interface that helps increase the efficiency of utilizing CPUs, GPUs, accelerators, and memory. SK hynix has participated in the CXL consortium from an early stage, and is looking to secure CXL memory market leadership.

The essential point of the CXL memory market is expandability. The CXL memory allows for flexible memory expansion compared to current server market, where the memory capacity and performance are fixed once the server platform is adopted. CXL also has high growth potential as it is an interface spotlighted for high performance computing systems such as AI and big data related applications.
