SK hynix has become the first in the industry to develop the High Bandwidth Memory 3, the world’s best-performing DRAM.
SK hynix’s HBM3 is the fastest DRAM in the world and comes with the biggest capacity and significantly improved level of quality.
The latest product 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 percent 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 will be provided 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.
Since its launch of the world’s first HBM DRAM, SK hynix has succeeded in developing the industry’s first HBM3 after leading the HBM2E market, said Seon-yong Cha, Executive Vice President in charge of the DRAM development.
