Samsung has announced the "industry-first" development of DRAM that combines DDR5 memory with the compute express link (CXL) connection. The OEM believes this kind of interface, based on PCIe 5.0, is the next big thing in datacenter, machine-learning and cloud computing, particularly when it comes to scalability.

Today, (May 11, 2021) Samsung has launched what it calls CXL-enabled DDR5, a new kind of memory module slated to overcome the traditional limitations of DDR (double-data rate) so as to unleash new horizons in high-performance, high-volume computing.

This, according to the OEM, is due to its new kind of interface, which is of an open standard based on PCIe 5.0. Samsung asserts that it should be adopted as it can overcome DDR's current memory-channel limits in order to "significantly scale memory capacity and bandwidth". CXL is rated to scale up to the terabyte level in fact, with "dramatic" drops in system latency.

Therefore, Samsung projects that CXL will enhance capacity, as well as bandwidth, "well beyond what is possible today" - on its commercialization, of course. AMD seems to have caught its enthusiasm for the emerging interface thus far, with its Server Business Unit's senior vice president Dan McNamara noting that the company is "excited to work with Samsung to deliver advanced interconnect technology to our data center customers”.
