OPENEDGES Completes the Tapeout of the 7nm HBM3 Memory Subsystem (PHY & Memory Controller) Test chip

Seoul, South Korea, March 23rd, 2023 --- OPENEDGES Technology, Inc. (OPENEDGES) today released a detailed update on the successful completion of the first tape out of an advanced 7nm process technology test chip for its HBM3 memory subsystem IP, including the PHY and memory controller. This update provides in-depth insights into the tape-out that represents the completion of the design phase, the beginning of silicon characterization and validation, and the expansion pathway to more silicon-proven IPs supporting the most up-to-date JEDEC DRAM standards.

The OPENEDGES 7nm HBM3 memory subsystem IP testchip was designed in compliance with the JEDEC JESD238 HBM3 standard, delivering up to 8.4Gbps data rates per IO in a 2.5D integration platform. The HBM3 PHY IP has the capability to support up to 16 independent and asynchronous channels, each with 2x32-bit DWORD pseudo-channels. Additional features include multiple frequency set points (FSPs), DBI, ECC, SEV, and Parity (data and command/address parity), as well as lane repair, also known as Interconnect Redundancy Remapping, which detects, repairs, and remaps repairable interconnect issues automatically, making them transparent to the memory controller.


Moreover, it’s equipped with a proprietary microcontroller for firmware-based training and a firmware-based API to work with DRAM’s IEEE 1500 for training and testing. Optimized traffic monitoring with power-down and self-refresh states improves power efficiency, and the out-of-order scheduling algorithm, combined with the highly optimized pipeline architecture, provides an efficient solution for applications requiring high memory bandwidth, particularly in the fields of artificial intelligence (AI), machine learning (ML), and general-purpose graphics processing units (GPGPU).


“We are very proud of the team in completing the development of this complex, large-scale IP, starting only from the JEDEC specification and taking all the way through the physical implementation of a test chip,” said Farhad Haghighi Zadeh, Principal Engineer at The Six Semiconductor of OPENEDGES Technology and Design Lead for the HBM3 program. “This project demonstrated our excellence in execution through cross-team collaboration.”


“As HBM3 can process vast amounts of data quickly, it is becoming more essential and recognized as an advanced technology that is necessary for the faster processing of big data,” said Sean Lee, the CEO of OPENEDGES Technology. “Taking advantage of OPENEDGES’ past success with various tape-outs, we will continue collaborating with our client to silicon-prove the HBM3 7nm memory subsystem IP and introduce it to the market”.


By incorporating an architecturally optimized approach to analog mixed-signal design and partitioning across its PHY IP portfolio, OPENEDGES is able to provide maximum ease of integration for its hard-IP components and enable the latest DDR standards even on older technology nodes. The PHY IPs offered by OPENEDGES support JEDEC-compliant standards, such as HBM3, GDDR6, and LPDDR5X/5/4X/4, in multiple foundries and technology nodes.
