Full-Scale Expansion of the CXL Ecosystem

Samsung Electronics has laid the groundwork for the commercialization of technology that expands capacity by integrating multiple semiconductors for the first time in the industry. This paves the way to enhance data processing and memory performance at a low cost, amid expectations that demand for artificial intelligence (AI) semiconductors such as High Bandwidth Memory (HBM) will surge starting next year.

On the 27th, Samsung Electronics announced that it successfully verified Compute Express Link (CXL) memory operation in collaboration with Red Hat, a global enterprise Linux company. They optimized CXL memory for the enterprise Linux operating system (OS) 'Red Hat Enterprise Linux' and verified memory recognition, reading, writing, and other functions. The company explained, "This operation verification establishes the foundation for CXL commercialization."

CXL is regarded as a technology that complements the limitations of existing memory semiconductors. It is a next-generation interface that efficiently connects computing systems such as Central Processing Units (CPU), Graphics Processing Units (GPU), and memory storage, enabling faster computational processing. It increases memory capacity by enhancing scalability while using the main DRAM of existing systems as is.

In particular, Samsung Electronics expects to dramatically change its lagging position in the HBM market through the development of CXL technology. HBM is connected to processing units like CPUs and GPUs, allowing fast data transfer, making it suitable for AI server training and computation. However, Samsung has been somewhat outpaced by SK Hynix. Through CXL, customers can use Samsung’s CXL memory without changing their software. This verification is the result of joint efforts by Samsung Electronics and Red Hat since May last year in software technology collaboration in the next-generation memory field.

Baek Yong-chul, Vice President of Product Planning at Samsung Electronics’ Memory Business Division, said, "It is a combination of cutting-edge hardware and software technologies," adding, "It will contribute to advancing the CXL ecosystem to the next level."
