Compute Express Link™ (CXL™) is an open industry-standard interconnect offering coherency and memory semantics using high-bandwidth, low-latency connectivity between the host processor and devices
There is a demand for Hierarchical memory as use cases demand higher amounts of memory capacity and bandwidth as AI/ML, database applications scale up and scale out.
Emergence of serial-attached protocols like CXL and OpenCAPI. It is possible to connect DRAM based devices in the same physical slot as NAND Flash SSD.
