▶128GB CXL DRAM based on advanced CXL 2.0 interface to be mass-produced this year, accelerating commercialization of next-generation memory solutions
▶Samsung will continue collaborating with a global data center, server, and chipset companies to bolster the CXL ecosystem

Recently, Samsung Electronics announced its development of the industry's first 128-gigabyte (GB) DRAM to support Compute Express Link™ (CXL™) 2.0. Samsung worked closely with Intel on this landmark advancement on an Intel® Xeon® platform.

Building on its development of the industry's first CXL 1.1-based CXL DRAM in May of 2022, Samsung expects that the 128GB CXL DRAM based on CXL 2.0 will accelerate the commercialization of next-generation memory solutions. The new CXL DRAM supports PCle 5.0 interface (x8 lanes) and provides up to 35GB per second bandwidth.

"As a member of the CXL Consortium Board of Directors, Samsung Electronics remains at the forefront of CXL technology," said Jangseok Choi, vice president of the New Business Planning Team at Samsung Electronics. "This breakthrough development underlines our commitment to expanding the CXL ecosystem even further through partnerships with the industry's data center, server, and chipset companies."

"Intel is delighted to work with Samsung on their investment towards a vibrant CXL ecosystem, said Jim Pappas, director of Technology Initiatives at Intel Corporation. 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 of Montage Technology. "We look forward to continuing our partnership with Samsung to advance CXL technology and expand its ecosystem."

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

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

CXL is a next-generation 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-generation computing market, where key technologies such as artificial intelligence (AI) and machine learning (ML) have led to a rapid rise in demand for high-speed data processing.

■삼성전자, 업계 최초 CXL2.0 기반 128GB CXL DRAM 양산 돌입

삼성전자는 최근 Compute Express Link™(CXL™) 2.0을 지원하는 128GB DRAM을 개발했다고 밝혔다. 

삼성전자는 지난해 5월 업계 최초로 CXL 1.1 기반 CXL DRAM을 개발한 데 이어, CXL 2.0 기반의 128GB CXL DRAM을 출시함에 따라 데이터센터의 성능을 한 단계 더 높은 성능까지 끌어 올렸다는 평가다. 

CXL은 고성능 컴퓨팅 시스템에서 CPU와 함께 사용되는 가속기, 메모리, 저장장치 등을 보다 효율적으로 활용하기 위해 개발한 인터페이스다. 기존 컴퓨팅 시스템의 메모리 용량의 물리적 한계를 극복하고 D램의 용량을 획기적으로 확장할 수 있다.

삼성전자는 인공지능, 머신러닝, 빅데이터 등 데이터센터의 성능을 획기적으로 개선할 수 있는 대용량·대역 D램 기술 개발을 통해 글로벌 주요 데이터센터, 클라우드 업체들과 협력을 확대해 나갈 방침이다. 

삼성전자 최장석 상무는 "삼성전자의 CXL D램 기술은 차세대 컴퓨팅, 대용량 데이터센터, 인공지능 등 미래 첨단분야에서 핵심 메모리 솔루션 역할을 할 것“이라며, “스마트 데이터센터가 요구하는 차세대 기술을 선도하고 CXL 생태계가 빠르게 확장될 수 있도록 글로벌 기업들과 협력을 강화해 나가겠다”고 밝혔다.
