You heard that right, not storage, but RAM!
During the Hot Chips 33 exhibit, Samsung formally announced the industry’s first-ever DDR5-7200 single-stick 512GB RAM! This makes your 64GB stick seem like it was from ten years ago.
The new RAM is based on a High-K Metal Gate processing technology (HKMG) which they claim to deliver twice the speed of DDR4 RAM at 7200Mbps. Samsung claims that this new DDR5 RAM will be able to handle even the most demanding and heaviest of tasks, such as artificial intelligence (AI), machine learning (ML), and data analytics. HKMG process technology is traditionally used in logic semiconductors
“Samsung is the only semiconductor company with logic and memory capabilities and the expertise to incorporate HKMG cutting-edge logic technology into memory product development,” said Young-Soo Sohn, Vice President of the DRAM Memory Planning/Enabling Group at Samsung Electronics. “By bringing this type of process innovation to DRAM manufacturing, we are able to offer our customers high-performance, yet energy-efficient memory solutions to power the computers needed for medical research, financial markets, autonomous driving, smart cities and beyond.”
The DDR5 RAM stacks eight layers of 16Gb DRAM chips through TSV (through-silicon-via [technology]). It is a massive improvement over the usual four layers, as this eight-layer DDR4 dies can now have a maximum capacity of 512GB. This TSV technology was first utilized back in 2014, when Samsung announced storage options that can load up to 256GB.
While this new DRAM technology certainly is exciting, don’t throw out your RAM chips yet! As Samsung has reflected more on ML and AI, then this RAM is ultimately meant for servers used in supercomputers.
