IBM fabs Micron memory cube with TSV tech

December 2, 2011 — Using the advanced through-silicon via (TSV) fabrication process at IBM (NYSE:IBM), Micron Technology Inc. (NASDAQ:MU) will begin producing its Hybrid Memory Cube. The companies claim that this is the first CMOS design to go commercial with TSV interconnects.

HMC parts will be manufactured at IBM’s advanced semiconductor fab in East Fishkill, NY, using the company’s 32nm, high-K metal gate (HKMG) process technology. IBM will present the details of its TSV manufacturing breakthrough at the IEEE International Electron Devices Meeting (IEDM) on December 5 in Washington, DC.

"This is a milestone in the industry move to 3D semiconductor manufacturing," said Subu Iyer, IBM Fellow. "The manufacturing process we are rolling out will have applications beyond memory, enabling other industry segments as well. In the next few years, 3D chip technology will make its way into consumer products, and we can expect to see drastic improvements in battery life and functionality of devices."

Micron’s Hybrid Memory Cube (HMC) reportedly achieves speeds 15 times faster than today’s technology. It combines high-performance logic with Micron’s state-of-the-art DRAM using TSVs. HMC prototypes show bandwidth of 128 gigabytes per second (GB/s), using 70% less energy to transfer data, and boast a form factor that is 10% of the footprint of conventional memory. Applications include large-scale networking and high-performance computing, industrial automation and high-end consumer products.

"HMC is a game changer, finally giving architects a flexible memory solution that scales bandwidth while addressing power efficiency," said Robert Feurle, VP of DRAM marketing for Micron.
