What is CMM-H?

The CMM-H device features Samsung’s high-performance DRAM, combined with NAND Flash and a CXL Type 3 interface. These technological characteristics are combined to offer a cost-effective memory expansion device. The motivation behind CMM-H is to combine DRAM speed and NAND Flash capacity with the CXL load/store memory interface. It presents large NUMA nodes with existing Linux kernel framework and seamlessly integrates with applications without the need for modification. CMM-H is a great design choice for applications that prioritize capacity, TCO, and throughput over random access latency. We offer two types of CMM-H: Persistent and Tiered Memory. CMM-H Persistent Memory comes with built-in data persistence to minimize down time during data recovery. The use case examples include in-memory databases and AI inferencing of large language models.
