Montage Technology Pioneers CXL 3.2 MXC Chip Trial Production, Adopted by Samsung and SK Hynix
In July 2026, Montage Technology began trial production of the industry's first CXL 3.2 MXC chip, supporting up to 64GT/s CXL and 8000MT/s DDR data rates. The chip has been integrated into next-generation CXL products from major memory module makers including Samsung and SK Hynix. Memory manufacturers are shifting from in-house development to third-party MXC chips, signaling a return to specialized division of labor in the CXL supply chain.
In July 2026, Montage Technology took the lead in the industry by commencing trial production of its CXL 3.2 MXC chip. The chip supports a maximum CXL data rate of 64GT/s and a DDR data rate of 8000MT/s, and has been successfully integrated into the next-generation CXL products of major memory module manufacturers such as Samsung and SK Hynix.
Related memory manufacturers have abandoned in-house development and shifted to sourcing third-party MXC chips. The CXL supply chain is returning to a specialized division of labor, with applications such as memory pooling and reuse of existing DRAM gradually being implemented.
