Samsung Electronics said Tuesday that it has developed the industry’s first 512-gigabyte Compute Express Link (CXL) DRAM module for servers that enables a higher memory capacity and lower latency suitable for artificial intelligence and cloud computing.

The CXL-standard DRAM memory expander will allow a server platform in data centers and enterprise servers to add new layers of short-term memory capacity compatible with a processor chip without unnecessary costs and complexities, as opposed to a chip architecture solely composed of memory chips under standards such as Double Data Rate 5.

The conventional DDR-based chip design, without the CXL memory interface interconnecting itself with DDR memory chips, limits memory capacity scaling to within the tens of terabyte range, according to the South Korean tech giant.

Samsung said in a statement the CXL-based memory chip is key for servers to handling gigantic amount of data workloads for the metaverse, AI and big data.

“CXL DRAM will become a critical turning point for future computing structures by substantially advancing AI and big data services, as we aggressively expand its usage in next-generation memory architectures including software-defined memory,” Park Cheol-min, vice president of memory global sales and marketing at Samsung Electronics, said in a statement.

The launch is a preemptive step before the next-generational server platform comes into being. According to the world’s No. 1 memory chip maker, the sampling for the 512-gigabyte CXL-based DRAM chips will begin with customers and partners for joint evaluation and testing in the third quarter. Samsung‘s partners for the CXL initiative include Lenovo and Montage.

This is a step up for the company’s move to standardize CXL. Since 2019, Samsung has been collaborating with data center, server and chipset makers to develop next-generation interface technology by forming the CXL Consortium. Samsung’s Park is a member on the CXL Consortium’s Board of Directors.

Samsung is the first chipmaker to have unveiled the CXL-based chip in the industry in 2021. The new product unveiled Tuesday features four times the memory capacity and one-fifth the system latency of Samsung’s previous CXL offering.
