SK Hynix develops the world's fastest high-bandwidth DRAM based on HBM2E

Supported speeds over 460GB/s with mass production expected to begin next year

SK Hynix develops the world's fastest high-bandwidth DRAM based on HBM2E

Hot on the heels of Samsung and its "Flashbolt" HBM2E memory, SK Hynix has now become the second DRAM manufacturer to announce its next-gen HBM2E that boast 3.6Gbps (vs 3.2Gbps of Samsung's Flashbolt) speed performance per pin with 1,024 data I/Os.

Offering a 50 percent jump over previous-gen HBM2, the next-gen HBM2E also has "100% additional capacity" according to SK Hynix. By vertically stacking eight 16-gigabit chips, packages of 16GB solutions will be possible through utilization of TSV (Through-silicon via) technique. For advanced hardware employing multiple stacks like server GPUs, 4-stack processors could be paired up with as much as 1.84TB/sec of memory bandwidth.

SK Hynix is aiming its DRAM at "high-end GPU, supercomputers, machine learning, and artificial intelligence systems that require the maximum level of memory performance," which the company says allows for faster data transfer owing to the HBM interface that results in the DRAM sitting ㎛ units apart from GPUs and logic chips as opposed to commodity DRAM products that take the shape of module packages and are mounted on system boards.

"SK Hynix has established its technological leadership since its world’s first HBM release in 2013,” said Jun-Hyun Chun, Head of HBM Business Strategy.
