About this actor

South Korean prosecutors indicted ten former Samsung executives and researchers in December 2025 for allegedly leaking 10nm-class DRAM technology to China-based CXMT; prosecutors say the transfer let CXMT mass-produce 10nm-class DRAM in 2023 and laid groundwork for its HBM efforts.
