NEC Offers Web-Deliverable DRAM Models Using Denali Memory Models

Denali's models support NEC's VC-SDRAM technology and the JEDEC specification

PALO ALTO, Calif.--(BUSINESS WIRE)--Oct. 4, 1999--Denali Software Inc. announced today that NEC Corporation (Nasdaq:NIPNY -news; Tokyo, Japan) is using Denali memory models for Web-based delivery of its external DRAM models. The Denali models support the Joint Electron Device Engineering Council standard (JEDEC standard JESD 21-C) as well as NEC's Virtual Channel (VC) SRAM technology.

When used with Denali's Memory Modeler, models for NEC's DRAM components give designers the capability to instantly access the most up-to-date and accurate models for system design and verification.

``NEC has always been focussed on providing our customers with superior technology and design support,'' said Hiroaki Ikeda, Senior Manager of LSI Memory Operations Unit, NEC Corporation. ``With Denali's SOMA language models, we provide a solution that enables our customers to verify their high-performance systems using our latest memory technology instantly, assuring maximum design quality and performance.''

Sanjay K. Srivastava, president of Denali Software, noted, ``This agreement is with one of the world's leading ASIC and DRAM suppliers. It is significant because it is another example of the growing importance of memory modeling for systems design, and the adoption of our SOMA format for Web-based delivery of memory models.''

Denali's Specification of Memory Architecture (SOMA) language memory models are found on NEC's Web Site at http://www.ic.nec.co.jp/memory/models/index.html.

Under the terms of the agreement between NEC and Denali, Denali is developing SOMA models for all existing and future external NEC DRAM devices such as SDRAM, DDR SDRAM and Rambus DRAM and VC-SDRAM.

About NEC's VC-SDRAM technology

VC-SDRAM decreases the time it takes to retrieve data from memory by temporarily storing data in multiple channels between the input/output terminals and memory cells. This allows the memory chip to prepare other memory data requests in a separate channel while reading or writing current data. The resulting throughput advantage is key in any system seeking higher performance to support such functions as soft modems and MPEG decompression needed in multi-media rich products like computers, set-top boxes and PC Graphics.

About Denali's Memory Vendor Partnership Program and Denali's

Memory Models

Denali established its Memory Vendor Partnership program in June, 1998. Currently the Company's SOMA models for SoC design are available from AMD, Cypress, Motorola, IBM, and Rambus, and are used by over 150 companies worldwide.

Denali's SOMA language is designed to provide high quality memory models to designers of electronic systems and enables distribution of models across the Internet and World Wide Web. Used with Denali Software's Memory Modeler, it offers easy portability of memory component libraries for use across all EDA simulation and verification environments. SOMA models and Memory Modeler allow designers to create models for new or existing memory components. Memory Modeler is integrated with popular hardware description language (HDL) simulators and provides a data-driven verification environment, accurate models and powerful and interactive debug capabilities. Price and Availability The Denali Memory Modeler and PureData are available at U.S. list prices of $7500 and $15,000, respectively, and are immediately available from Denali Software. This includes SOMA language support and support for Verilog and VHDL. Denali models and tools run on Solaris, SunOS, Windows NT/95, HPUX, Compaq Tru64 UNIX, IRIX and AIX operating systems.
