Compute Express Link (CXL) interconnection technology, which minimizes latency while increasing memory scaling to Tb level, comes to life in Samsung DRAM products.
Compute Express Link (CXL) internal link technology, which industry giants have been working on for 6 years, is gradually coming to life. Samsung announced the development of the first CXL linked DRAM memory module.
What is CXL?
The processor or graphics unit communicating with other components at high speeds also affects performance. While Nvidia uses NVLink technology for communication, AMD uses InfinityFabric technology. Intel also pressed the button in 2015 for an open source interconnection technology.
The Compute Express Link (CXL) Consortium, created under the leadership of Intel, announced the Compute Express Link gen 1 - CLX 1.0 technology in 2019. Based on the PCIe 5.0 standard, this technology offers a data transfer rate of 32Gbps per line. Compliant with previous PCIe standards as electrical interface and physical layer. Thus, the cost of upgrades in data centers will be reduced.
Samsung, one of the members of the consortium, announced that it has developed the industry’s first CXL-based DRAM memory module. Unlike conventional memory, the module to be integrated into DDR5 memory increases the scaling to the Tb level and minimizes the latency caused by the cache.
In addition, different software such as controllers developed by Samsung, memory mapping, interface conversion and error management are also integrated into the DDR5 memory. Samsung started negotiations with customers for CXL-based DDR5 memory, which will increase efficiency in servers and data centers.
