About

Fabless IC design company selling interconnect chips (memory-interface, clock, PCIe retimer, CXL memory controller) and the Jintide server platform for cloud computing, data centers, and AI infrastructure. Reported FY2025 revenue of about RMB 5.5B with unusually high margins for a Chinese fabless company.

Why it matters

Memory-interface chips sit between DRAM and the CPU in every server, and Montage holds real share in that global, standards-driven niche — making it one of the few Chinese fabless companies competing worldwide rather than substituting domestically. Its DDR5 interface and CXL roadmap is a clean read on whether that position holds through the AI server cycle.
