The company worked closely with Intel Corp. on this landmark advancement on a Xeon platform.

Building on its development of a industry’s first CXL 1.1-based CXL DRAM in May of 2022, Samsung’s introduction of the 128GB CXL DRAM based on CXL 2.0 is expected to accelerate commercialization of next-gen memory solutions. This CXL DRAM supports PCle 5.0 interface (x8 lanes) and provides bandwidth of up to 35GB/s.

As a member of the CXL Consortium Board of Directors, Samsung Electronics remains at the forefront of CXL technology,” said Jangseok Choi, VP, new business planning team, Samsung Electronics. “This breakthrough development underlines our commitment to expanding the CXL ecosystem even further through partnerships with data center, server and chipset companies across the industry.

Intel is delighted to work with Samsung on their investment towards a vibrant CXL ecosystem,“ said Jim Pappas, director, technology initiatives, Intel .“Intel will continue to work with Samsung to foster the growth and adoption of innovative CXL products throughout the industry.”

Montage is excited to mass produce the first controllers to support CXL 2.0,” said Stephen Tai, president, Montage Technology. “We look forward to continuing our partnership with Samsung to advance CXL technology and expand its ecosystem.”

For the 1st time, CXL 2.0 supports memory pooling – a memory management technique that binds multiple CXL memory blocks on a server platform to form a pool and enables hosts to dynamically allocate memory from the pool as needed. This technology allows customers to maximize efficiency while lowering operating costs, which will in turn help customers reinvest resources into reinforcing their server memory.

The company plans to start mass producing CXL 2.0 DRAM later this year and is poised to deliver additional offerings in various capacities to address demand for future computing applications.

CXL is a next-gen interface that adds efficiency to accelerators, DRAM and storage devices used with CPUs in high-performance server systems. Given that its bandwidth and capacity can be expanded when used with the main DRAM, the technology’s advancement is expected to make waves across the next-gen computing market, where key technologies such as AI and ML have led to a rapid rise in demand for high-speed data processing.
