Overview

Discover HBM2!

SK hynix continues to lead the memory industry through the successful development of the world’s first HBM and other next-generation memory solutions incorporating the innovative TSV(Through Silicon Via) technology.
HBM2, the next-generation solution of HBM1, provides world-class performance through higher bandwidth (over 256GB/s) and lower power consumption in comparison to other conventional DRAMs.
The leading edge features and technology of SK hynix’s HBM2 will enrich your experience with groundbreaking system performance for various applications, including those of: graphics, servers, supercomputer, networking and many more.

Leading Memory Solutions for Various Applications

HBM is a leading edge memory solution which was first adopted by high-end graphics cards. It is known to have provided the best solutions possible through implementation of 3D, 4K display, Virtual Reality and other upgraded functions.
The usage of HPC(High-performance computing) has extended to various applications in the purpose of processing and storing huge amounts of big data. A high density memory using TSV stacking technology, HBM answers calls for cost-effective memory solutions, securing its reputation as “the most effective” memory for HPC and related products.
In other words, HBM, which has advantages in high performance, low power and small form factor, will help overcome DRAM maximum speed and density limitations which will result in the explosive expansion of HBM demand.

Why HBM? Increased Bandwidth and Lower Power Consumption!

HBM outperforms GDDR5 in memory bandwidth and also in power consumption.
