SK hynix samples 12-layer HBM3 chip with 24 GB capacity

SK hynix announced sampling of the first 12-layer HBM3 product with a 24 GB memory capacity -- the largest in the industry to date. 

HBM (High Bandwidth Memory) vertically interconnects multiple DRAM chips and dramatically increases data processing speed in comparison to traditional DRAM products. HBM3 is the 4th generation product, succeeding the previous generations HBM, HBM2 and HBM2E.

"The company succeeded in developing the 24GB package product that increased the memory capacity by 50% from the previous product, following the mass production of the world's first HBM3 in June last year," SK hynix said. "We will be able to supply the new products to the market from the second half of the year, in line with growing demand for premium memory products driven by the AI-powered chatbot industry."

SK hynix said the gains in process efficiency and performance stability were achieved by applying Advanced Mass Reflow Molded Underfill (MR-MUF) technology to the latest product, while Through Silicon Via (TSV) technology reduced the thickness of a single DRAM chip by 40%, achieving the same stack height level as the 16GB product.
