Samsung Launches 16GB HBM2E with Stable Data Transfer Speed at 3.2Gbps

Samsung today announced the market launch of Flashbolt, its third-generation High Bandwidth Memory 2E (HBM2E). Ready to deliver twice the capacity of the previous-generation 8GB HBM2  Aquabolt , the new Flashbolt  sharply increases performance and power efficiency to significantly improve next-generation computing systems. The 16GB capacity is achieved by vertically stacking eight layers of 10nm-class (1y) 16-gigabit (Gb) DRAM dies on top of a buffer chip. This HBM2E package is then interconnected in a precise arrangement of more than 40,000  through silicon via  (TSV) microbumps, with each 16Gb die containing over 5,600 of these microscopic holes.

Samsung’s new 16-gigabyte (GB) HBM2E provides a highly reliable data transfer speed of 3.2 gigabits per second (Gbps) by leveraging a proprietary optimized circuit design for signal transmission, while offering a memory bandwidth of 410GB/s per stack. Samsung’s HBM2E can also attain a transfer speed of 4.2Gbps, the maximum tested data rate to date, enabling up to a 538GB/s bandwidth per stack in certain future applications. This would represent a 1.75x enhancement over Aquabolt’s 307GB/s.
