Samsung Announces Upgraded 512GB CXL Memory Module

Samsung has presented the first memory module which has been based on four times more DRAM than the previous version. The company’s first-ever 512GB Compute Express Link (CXL) memory module will allow it to provide huge amounts of memory to the servers without causing a great deal of stress on the system latency.

All of these models are based on a DDR5 RAM and are considered as the main memory by both the GPU as well as the CPU. This serves as the major role of the CXL form factor which provides huge memory capacities in tens of TB. It allows the users to amass huge amounts of memory and bandwidth in data centers and will come with a high-speed PCI Express 5.0 bus.

These modules are not just about their special technique of finding their way around memory capacity limits but also know their way around the system latency as they are not too taxing on the systems. With the help of memory caching, these CXL-enabled modules reduce the system latency meanwhile also increasing the bandwidth of many TBs per second.


According to Cheolmin Park, the Vice President of Memory Global Sales & Marketing at Samsung Electronics, and Director of the CXL Consortium:
“CXL DRAM will become a critical turning point for future computing structures by substantially advancing artificial intelligence (AI) and big data services, as we aggressively expand its usage in next-generation memory architectures including software-defined memory (SDM)”

With the popularity for Metaverse on the rise and many related tech experiences coming into play, Samsung doesn’t see the CXL modules as a big bet; they see them having quite a few opportunities in the emerging market particularly the AI driven workloads which will require huge memory capacities. This is where the newest upgraded 512GB CXL module will come in handy; it will be the first ever memory device of its kind which will provide support for PCIe 5 and will be based on the EDSFF (E3.2) form factor.

Additionally, Samsung has also announced that it will be unveiling the updated version of its open source Scalable Memory Development Kit (SMDK). The SMDK will be a comprehensive toolkit working in collaboration with the CXL module memory expander allowing it to work seamlessly with the memory systems.
