World’s First High Bandwidth Memory 3 From SK hynix Can Process Up to 819GB Per Second

SK hynix today became the first in the industry to successfully develop the High Bandwidth Memory 3, the world’s best-performing DRAM. HBM3, the fourth generation of the HBM technology with a combination of multiple DRAM chips vertically connected, is a high value product that innovatively raises the data processing rate. The latest development, which follows the start of mass production of HBM2E in July last year, is expected to help consolidate SK hynix’s leadership in the market. SK hynix is the first in the industry to start mass production of HBM2E.

SK hynix’s HBM3 is not only the fastest DRAM in the world, but also comes with the biggest capacity and significantly improved level of quality. SK hynix’s HBM3 can process up to 819GB (Gigabyte) per second meaning that 163 FHD (full-HD) movies (5GB each) can be transmitted in a single second. This represents a 78% increase in the data-processing speed compared with the HBM2E. It also corrects data (bit) errors with the help of the built-in on-die error-correction code, significantly improving the reliability of the product.

SK hynix’s HBM3 is available in two capacity types of 24GB – the industry’s biggest — and 16GB. For the 24GB product, SK hynix engineers ground the height of a DRAM chip to approximately 30 micrometer (μm, 10-6m), equivalent to a third of an A4 paper’s thickness, before vertically stacking 12 chips using the through silicon via technology. HBM3 is expected to be mainly adopted by high-performance data centers as well as machine learning platforms that enhance the level of artificial intelligence and supercomputing performance used to conduct climate change analysis and drug development.
