GUC Reveal World’s First HBM3 PHY, Controller, and CoWoS Platform at 7.2 Gbps

//php echo do_shortcode(‘[responsivevoice_button voice=”US English Male” buttontext=”Listen to Post”]’) ?>

International Unichip Corp. (GUC), the chief in Superior ASIC, introduced that they’ve silicon out there which proved their 7.2 Gbps HBM3 answer, utilizing SK hynix’s first out there HBM3 samples. The platform was demonstrated on the Companion Pavilion of the TSMC 2022 North America Expertise Symposium; it contained an HBM3 Controller, a PHY, GLink-2.5D die-to-die interface, and a 112G SerDes. The platform helps each the TSMC CoWoS-S (silicon Interposer) and the CoWoS-R (natural interposer) superior packaging applied sciences.

The platform represents real-world CPU/GPU/AI/Networking chips by integrating a number of HBM3 reminiscences, GLink-2.5D die-to-die interfaces, and 112G-LR lanes in a excessive energy (as much as 400 W) SoC. GUC designed the SoC chip, interposer, substrate and DFT to satisfy excessive energy and excessive velocity requirement on the system stage; managed the consigned supplies and last testing with in depth operation expertise; and labored with TSMC on CoWoS bundle meeting.

The HBM3 PHY and Controller IP are prepared for top yield manufacturing at 7.2 Gbps. GUC’s patent-pending interposer design permits HBM3 bus routing between PHY and reminiscence at any angle whereas retaining the identical sign high quality as in common straight HBM bus routing. It additionally offers a excessive flexibility for the SoC and interposer floorplan. GUC’s patented answer allows a reminiscence bus of 1 HBM3 die to be cut up into two Controller/PHY pairs in two separate SoC dies. This distinctive function allows the configuration of two:6 or 2:10 SoC vs. HBM3 use instances.

SK hynix’s HBM3 – used for GUC’s Controller, PHY, and platform – offers as much as 819 GB/s of bandwidth. “Not too long ago we began mass manufacturing of HBM3 and are proving the world’s first readiness of HBM3 and its greatest efficiency.” stated Sungsoo Ryu, head of DRAM product planning at SK hynix, “By this cooperation, SK hynix and GUC have been in a position to verify their partnership throughout the HBM ecosystem. We admire this collaboration as a chance to show the world’s greatest HBM3 answer and solidify our management within the premium DRAM market.”

“We’re proud, along with TSMC and SK hynix, to display a first-in-the-industry HBM3 answer. Our HBM3 Controller and PHY are primarily based on the very long time and high-volume manufacturing expertise of GUC’s CoWoS/HBM2 merchandise. At 7.2 Gbps we’re prepared for the ever-growing velocity necessities of our prospects.”, stated Jentai Hsu, vp of GUC. “GUC has a singular mixture of HBM3, GLink-2.5D and GLink-3D IP portfolio, CoWoS, InFO_oS, 3DIC design experience, bundle design, electrical and thermal simulations, DFT and manufacturing testing, excessive quantity manufacturing expertise to allow quick growth, and fast manufacturing ramp-up of the best finish CPU/GPU/AI/Networking merchandise.”


Key options of GUC’s HBM3 CoWoS Platform:

  • World’s 1st totally purposeful HBM3 Controller and PHY, production-ready at 7.2 Gbps
  • CoWoS interposer and bundle meet tight 112G-LR SerDes necessities
  • GLink-2.5D interface connecting a number of dies over CoWoS
  • GUC’s patent-pending interposer routing to assist HBM3 bus routing at any angle
  • Helps each TSMC’s CoWoS-S and CoWoS-R applied sciences
