Showcasing the Industry’s Highest Standard of AI Memory
The AI revolution has continued to pick up pace as AI technologies spread their reach into various industries. In response, SK hynix is developing AI memory solutions capable of handling the vast amounts of data and processing power required by AI. At GTC 2024, the company is displaying some of these products, including its 12-layer HBM3E and Compute Express Link (CXL)1, under the slogan “Memory, The Power of AI”.
1Compute Express Link (CXL): A PCIe-based next-generation interconnect protocol on which high-performance computing systems are based.

HBM3E, the fifth generation of HBM2, is the highest-specification DRAM for AI applications on the market. It offers the industry’s highest capacity of 36 gigabytes (GB), a processing speed of 1.18 terabytes (TB) per second, and exceptional heat dissipation, making it particularly suitable for AI systems. On March 19, SK hynix announced it had become the first in the industry to mass-produce HBM3E.
2High Bandwidth Memory (HBM): A high-value, high-performance product that possesses much higher data processing speeds compared to existing DRAMs by vertically connecting multiple DRAMs with through-silicon via (TSV).

Displayed alongside HBM3E is CXL, a standardized interface that increases the efficiency of utilizing CPUs, GPUs, accelerators, and memory. CXL is renowned for its ability to expand memory and improve the performance of AI applications. It is therefore set to play a key role in the AI era along with HBM3E. Visitors to SK hynix’s booth can also check out some never-before-seen products, including the next-generation GDDR7 DRAM specialized for video and graphics processing. Compared to its predecessor GDDR6, the latest GDDR3 product offers double the maximum bandwidth (128 GB per second), a 40% improvement in power efficiency, and enhanced visuals due to its expanded memory density. Set to be used in graphics cards and GPUs, GDDR7 will be integral for AI and advanced technologies which require rapid and large-capacity data processing.
3Graphics DDR (GDDR): A standard specification of graphics DRAM defined by the Joint Electron Device Engineering Council (JEDEC) and specialized for processing graphics more quickly. Its generation shifted from GDDR3, GDDR5 and GDDR5X to GDDR6. It’s now one of the most popular memory chips for AI and big data applications.
