Samsung Electronics announced that CXL technology is rapidly emerging as a next-generation solution for the AI era by overcoming the limitations of DRAM capacity and performance expansion.

On the 18th, Samsung Electronics held a briefing session on the topic of ‘Samsung Electronics CXL Solution.’

CXL (Compute Express Link) is a next-generation interface that efficiently connects various devices such as CPUs, GPUs, and storage to enable faster computational processing, with the meaning of 'fast connection and computation'.

CMM-D (CXL Memory Module-DRAM), a CXL-based DRAM, can efficiently process large amounts of data by connecting various types of processors into a single system.

It is also emerging as a next-generation solution for the AI era as it can improve the capacity and performance expansion limits of DRAM.

As demand and development of AI accelerate, the amount of AI learning and inference data processing is increasing explosively.

On the other hand, DRAM used in existing servers can only expand capacity within a limited range, so as AI technology advances, there are limitations in processing large amounts of data.

Therefore, it uses a high-speed interface and is easy to expand capacity.A CXL-based DRAM product is gaining attention as a next-generation memory solution.

CXL DRAM solutions, which can coexist with existing DRAMs and expand bandwidth and capacity within the system, are expected to receive more attention in the next-generation computing market that requires explosive data processing.

In order to expand the capacity of a data center or server, additional servers had to be added, but by simply inserting a CMM-D into the same spot where an SSD was inserted in an existing server, capacity can be conveniently expanded.

In particular, Samsung Electronics' 'CXL 2.0 DRAM', which was developed in May of last year, is the first in the industry to support the 'memory pooling' function.

'Memory pooling' is a technology that creates a pool by combining multiple CXL memories on a server platform, and allows each host to share and use as much memory as it needs from the pool.

This allows the full capacity of CXL memory to be used without any idle areas, reducing data transfer bottlenecks.

In the case of data centers, there is also the advantage of being able to reduce server operating costs through efficient memory use, which can reduce the total cost of ownership (TCO).

Samsung Electronics is leading the industry by successfully developing the industry's first CXL-based DRAM product in May 2021, the industry's highest capacity 512GB CMM-D, and the industry's first CMM-D 2.0.

Samsung Electronics introduced various CXL-based solutions, including CMM-D, a CXL-based DRAM, CMM-H (Hybrid) that uses DRAM and NAND together, and CMM-B (Box), a memory pooling solution, at the global semiconductor conference 'MemCon 2024' held in March.

Also 2 minutes this yearWe have launched a 256GB (gigabyte) CMM-D product supporting CXL 2.0 and are conducting verification with major customers.

In addition, as the first in the industry to have a CXL infrastructure certified by Linux vendor Red Hat, all server components, from CXL-related products to software, can be verified at the Samsung Memory Research Center.

Samsung Electronics is one of the 15 board members that formed the CXL Consortium, and is the only memory company to be selected as a board member, playing a role in advancing and standardizing CXL technology.

Big tech companies such as Samsung Electronics, Alibaba Group, AMD, Arm, Cisco Systems, Dell EMC, Google, Hewlett Packard Enterprise, Huawei, IBM, Intel, Meta, MS, Nvidia, and Rambus are participating as board members.

Since the launch of the CXL Consortium in 2019, Samsung Electronics has been actively working to expand the CXL ecosystem together with major global data center, server, chipset, and memory companies.
