01 — Overview
In the CXL Memory portfolio
SK hynix's CMM-DDR5 packages 96 GB of the company's DDR5 DRAM behind a CXL 2.0 controller on PCIe 5.0 x8. Added to a fully populated server, the module extends capacity by up to 50% and aggregate memory bandwidth by around 30%, since CXL traffic bypasses the DIMM channels.
SK hynix supports deployment with its HMSDK software kit, which handles page placement and bandwidth-aware interleaving across native and CXL tiers. The module suits stepwise memory scaling in cloud and database fleets without platform redesign.
