Denaliís Databahn Memory Controller Cores Achieve Production/Gold Status in UMCís IP Program

11/19/2002 - Denali Software, the leading provider of semiconductor intellectual property (SIP) and engineering design automation (EDA) tools for memory system design and verification, announced that its DatabahnTM memory controller cores have been fully qualified in production silicon for the first time at a pureplay semiconductor foundry. The cores are now characterized at the gold level (production verified) on UMCís (NYSE; UMC) 0.15 and 0.18 micron process technologies, and are in UMCís Gold IPTM catalog. Fabless semiconductor companies and integrated device manufacturers (IDMs) using UMC now have access to a silicon proven memory controller solution that is fully configurable for high-performance operation in a wide range of system-on-a-chip (SoC) applications.

"Our customers value the depth of the Databahn memory controller solution," said Kevin Silver, Vice President of Marketing at Denali. "Weíre providing more than just control logic for the memory interface. Weíve created an end-to-end solution that is fully configurable for a wide variety of control features, memory configurations, and board layouts. This also includes delay compensation circuitry for data capture/send to ensure reliable, high-frequency operation. Having this proven in UMCís process gives designers the additional level of confidence that they can go to UMC and realize an optimal memory system with shorter development times and lower risk."

"By working with Denali, we were able to configure thier Databahn memory controller core to perform exactly as required by our system design," said Richard Takahashi, CEO and president of Corrent Corporation. "Our network family of security chips incorporates a Databahn controller configured for DDR 133MHz operation (266MHz data transfers) with ECC (Error Correction Code) and support for various memory device configurations. These chips are now in production using UMCís 0.15 micron process technology. The quality of support we received from Denali and UMC throughout the process has been outstanding, we look forward to using Databahn again in upcoming chip designs."

"We are delighted that so many of Denaliís customers choose to manufacture their designs on UMCís deep submicron semiconductor processes, and that UMC is the first pureplay foundry to verify the Databahn cores in production silicon. Databahn makes an excellent addition to our IP catalog as it results in increased memory system IP options for our customers. The addition also puts UMC in the position of being the only foundry to offer fully qualified memory subsystem IP," said Dr. C.T. Lee, vice president of corporate marketing at UMC."

About Databahn
The Databahn solution enables designers to customize a memory controller core to meet performance and interface requirements for their ASIC application. Customization is supported through an online infrastructure at Denaliís site. A browser-based GUI enables fast efficient configuration of various performance and interface options, and also enables simulation-based performance validation. To ensure compatibility with all the latest high-speed memory technologies, the configuration process is tightly integrated with Denaliís database of memory component specifications, including all the latest DDRII-SDRAM, DDR-SDRAM, FCRAM, RLDRAM, and DDR/QDR-SRAM devices. Deliverables include: RTL and synthesis scripts, verification testbench, static timing analysis (STA) scripts, programmable register settings, and documentation. The silicon-proven Databahn IP is library independent and covers solutions from .18-micron to .08-micron technologies, and DRAM device frequencies from 100-400MHz (200-800MHz data rate).
