Samsung develops 128GB DRAM for data intensive applications

Samsung Electronics Co. said on Friday it has developed the industry’s first 128-gigabyte DRAM based on the compute express link (CXL) 2.0 memory used in high-performance server systems.

The latest CXL was developed on an Intel Xeon platform. Montage Technology Co. will mass produce the DRAM chips based on the CXL 2.0. technology from later this year.

CXL 2.0 is an upgraded version of the CXL 1.1-based DRAM Samsung unveiled last year. The CXL 1.1 model was also the world's first of its kind.

The CXL memory is an advanced hardware interface that processes high-performing computing systems faster than existing ones and is dubbed a next-generation memory system.

An interface is used to connect a central processing unit (CPU), a graphic processing unit (GPU) and memory chips to other electronics goods.

A typical server is equipped with up to 16 DRAM modules for every CPU. By comparison, a server using CXL-based memory can accommodate more DRAM.

The world’s largest memory chipmaker said the latest CXL model would accelerate data processing for new technologies such as artificial intelligence and the metaverse.

Jangseok Choi, vice president of Samsung's new business planning team, said in a statement that the company would expand the CXL ecosystem "even further through partnerships with data centers, as well as server and chipset companies across the industry."

Meanwhile, both Intel and Montage Technology have joined forces with SK Hynix Inc. to develop CXL technologies.
