Samsung Electronics Co. is intensifying its efforts in securing a stronghold in the CXL (Compute Express Link) memory technology domain. During a media briefing, Jangseok Choi, Vice President of Samsung's new business planning team, unveiled the company's intention to commence mass production of 256 GB DRAM modules that support the CXL 2.0 standard by the year's end.

CXL technology is anticipated to be a game-changer for high-performance server systems, providing a unified interface for various components including accelerators, DRAM, and storage devices that operate alongside CPUs and GPUs. Samsung projects that the adoption of CXL technology will result in an eight to tenfold increase in memory capacity per server, translating to a substantial leap in computational capabilities.

Samsung's extensive investment in CXL development is drawing to a close, with the company in the final stages of product testing with partners to ensure performance meets expectations. The company has also established the industry's first CXL infrastructure, certified by Red Hat, demonstrating its commitment to pioneering technology.

Choi provided insights into Samsung's new CXL Memory Module (CMM) technology, explaining that it allows for additional memory in spaces traditionally reserved for SSDs. This innovation is designed to bolster the CPU's capacity to handle large data transfers around the main memory, effectively complementing current DRAM functionalities.

A pivotal feature of Samsung's CXL 2.0 DRAM, which was developed in May 2023, is the memory pooling capability. This allows for the aggregation of multiple CXL memories on a server platform into a shared pool. Servers can then draw from this pool as needed, leading to optimized resource allocation, more efficient use of memory capacity, reduced data transfer bottlenecks, and an overall improvement in system performance and adaptability.

Samsung anticipates the CXL market to flourish in the second half of the year, with explosive growth expected from 2028 onwards, underlining the transformative potential of CXL technology in expanding memory capacity and bandwidth beyond current constraints.
