Samsung introduces the first 128GB CXL 2.0 DRAM

Samsung has unveiled the first 128GB CXL DRAM, which supports CXL 2.0. It uses Memory pooling technology to allow the full capacity of the CXL memory to be used without any free areas.

CXL (Compute Express Link) DRAM can co-exist with the main DRAM to expand bandwidth and capacity, so it is attracting attention in the next-generation computing market that requires high-speed data processing such as artificial intelligence and machine learning.

Samsung CXL 2.0 DRAM supports PCIe 5.0 (x 8 lanes) and provides 35Gb/s bandwidth. The PCIe (Peripheral Component Interconnect Express) is a high-speed interface standard that overcomes the performance limitations of existing SATA transmission speeds.

CXL 2.0 DRAM uses the industry’s first memory pooling function that binds multiple CXL memory on a server platform to form a pool, allowing multiple hosts to partition and use memory from the pool as needed.

If customers implement this technology in their data centers, memory can be used more efficiently, thereby reducing server operating costs. Furthermore, the virtuous cycle structure is expected to continue, such as the reinvestment of lower operating costs in memory for servers.

The Korean tech giant plans to mass-produce CXL 2.0 DRAM this year and timely launch products of various capacities according to the needs of the next-generation computing market, thereby becoming part of the CXL ecosystem.

Back in May 2022, Samsung Electronics was the world’s first to develop CXL 1.1-based CXL DRAM and the company has developed a 128GB DRAM that supports CXL 2.0 within a year, ushering in the era of next-generation memory commercialization.

The head of the new business planning team at Samsung Electronics’ memory division, Choi Jang-Seok said,

“Samsung Electronics is leading CXL technology as a member of the Board of Directors (BoD) of the CXL Consortium. With this, we will further expand the CXL ecosystem.”
