Odaily Planet Daily reports: Analyst Jukan from Citrini posted on X that the world's three largest memory chip manufacturers have ceased in-house development of Compute Express Link (CXL) controllers and are now adopting chips designed by external fabless companies.
Samsung Electronics, SK hynix, and Micron have all scaled back or canceled plans to commercialize CXL expansion device controllers. Micron has been the first to halt its in-house controller development and adopted PrimeMass’s solution; SK hynix has also informed its key partners of the termination of its internal CXL controller development project, reallocating personnel to processing-in-memory (PIM) initiatives. Samsung Electronics continues to use its in-house CXL controller solely for internal research purposes, while its external products are reportedly sourced from fabless suppliers. Industry insiders indicate that Samsung has removed its in-house controller from formal commercialization projects, retaining it only as a cutting-edge research initiative.
