Marvell advances its high-speed interconnects on TSMC's 3nm node

Marvell demonstrated high-speed, ultra-high bandwidth silicon interconnects produced on TSMC's 3-nanometer (3nm) process. This includes Marvell's 112G XSR SerDes (serializer/de-serializer), Long Reach SerDes, PCIe Gen 6 / CXL 3.0 SerDes, and a 240 Tbps parallel die-to-die interconnect.

SerDes and parallel interconnects serve as high-speed pathways for exchanging data between chips or silicon components inside chiplets. Together with 2.5D and 3D packaging, these technologies will eliminate system-level bottlenecks to advance the most complex semiconductor designs. SerDes also help reduce pins, traces and circuit board space to reduce cost. A rack in a hyperscale data center might contain tens of thousands of SerDes links.

The new parallel die-to-die interconnect, for example, enables aggregate data transfers up to 240 Tbps, 45% faster than available alternatives for multichip packaging applications. 

Marvell incorporates its SerDes and interconnect technologies into its flagship silicon solutions including Teralynx switches, PAM4 and coherent DSPs, Alaska Ethernet physical layer (PHY) devices, OCTEON processors, Bravera storage controllers, Brightlane™ automotive Ethernet chipsets, and custom ASICs. Moving to a 3nm process enables engineers to lower the cost and power consumption of chips and computing systems while maintaining signal integrity and performance.

"Interconnects are taking on heightened importance as clouds and other computing systems grow in size, complexity and capability. Our advanced SerDes and parallel interfaces will play a significant role in providing a platform for developing chips with best-in-class bandwidth, latency, bit error rate, and power efficiency for meeting the demands of AI and other complex workloads," said Raghib Hussain, president of products and technologies at Marvell. "We are proud to be able to deliver such advances on TSMC's 3nm technology and take semiconductor designs to the next level for our customers around the world."

  • Marvell was also the first data infrastructure silicon supplier to respectively sample and commercially release the 112G SerDes and has been a leader in data infrastructure products based on TSMC's 5nm process.

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.

OCP Switch Abstraction Interface moves under LF's DENT Project

The Linux Foundation (LF) announced the incorporation of the Open Compute Switch Abstraction Interface (SAI) into the open source DENT Network Operating System (NOS) project.

The DENT project, a Linux-based network operating system (NOS), has been designed to empower disaggregated networking solutions for enterprises and data centers. 

The Linux Foundation said that by incorporating OCP's SAI, an open-source Hardware Abstraction Layer (HAL) for network switches, DENT has taken a significant step forward in enabling seamless support for a wide range of Ethernet switch ASICs, thereby expanding its compatibility and fostering greater innovation in the networking space.

The move is driven by the need to widen standardized interfaces for programming network switch ASICs, enabling hardware vendors to develop and maintain their device drivers independently from the Linux kernel. SAI offers several advantages:

  • Hardware Abstraction: SAI provides a hardware-agnostic API, enabling developers to work on a consistent interface across different switch ASICs, thus reducing development time and effort.
  • Vendor Independence: By separating the switch ASIC drivers from the Linux kernel, SAI enables hardware vendors to maintain their drivers independently, ensuring timely updates and support for the latest hardware features.
  • Ecosystem Support: SAI is backed by a thriving community of developers and vendors, ensuring continuous improvements and ongoing support for new features and hardware platforms.
