Denali’s New CellularRAM™ Memory Simulation Models to Speed Development of 2.5G and 3G Handset Design

7/23/2002 - Denali Software, Inc., the leader in memory system design and verification, today announced the availability of high-performance simulation models for recently announced CellularRAM memory. Micron Technology, Inc., [NYSE: MU] and Infineon Technologies [DAX/NYSE: IFX] both anticipate shipping CellularRAM memory to customers within twelve months.

CellularRAM memory, a pseudo static RAM, addresses the high bandwidth and capacity needs of next-generation 2G and 3G handset designs. CellularRAM memory provides the most cost effective solution combining SRAM performance with the higher densities of DRAM, CellularRAM memory is a pin-compatible, refresh free, extremely low power drop-in replacement for SRAMs now used in handset designs.

Denali developed the CellularRAM memory models using its SOMA™ modeling technology. Denali released these models on a limited basis to developers of components for cellular designs. ARM Ltd. of Cambridge, UK, is one company that accessed Denali CellularRAM memory models earlier this year. ARM has used Denali memory models to aid development of its latest generation of memory controller IP for the ARM® PrimeCell® peripheral product range.

"We have verified the operation of our memory controllers with various memory devices using Denali memory models," said John Slater, PrimeCell Program Manager at ARM. "Our newest PL093 memory controller interfaces a variety of asynchronous and synchronous RAM, ROM, and flash memories including the new CellularRAM. The advantage of Denali Models for us is that we know how to use them. They are easy to integrate into our tool flow and we trust them. On recent memory controller projects, the models saved us time, engineering resources, and enabled us to deliver our IP ahead of the availability of some of the memories it supports."

"Micron is always looking for ways to provide customers access to resources to develop system-level products that take advantage of emerging memory architectures," said Mario Fazio, Micron Technology, Inc.’s, Director of Strategic Marketing for Wireless Products. "Providing simulation models for next-generation memory products enables designers to utilize the performance benefits of advanced technology in their designs without increasing their time to market. Denali’s modeling technology simplifies the integration of advanced memory technologies, such as CellularRAM, into system designs."

"Denali has developed and released memory models for Infineon’s Commodity and Specialty DRAM products, such as the Reduced Latency DRAM (RLDRAM) developed in a second cooperative agreement we have with Micron," said Ernst Strasser, Director of Marketing for Graphics and Specialty DRAM at Infineon Technologies. "This is a key milestone in creating the technology infrastructure required to efficiently bring state-of-the-art technology to market."

"No market is more competitive than cell phone handsets," said David Lin, Vice President of Applications Engineering of Denali. "Working with leading memory providers, such as Micron and Infineon, we’re able to provide our customers advanced access to the highest-quality simulation models available for leading-edge memory components like the CellularRAM device. We’re already experiencing strong interest in the CellularRAM memory model, and expect even greater interest."
