Nassda's HSIM Selected by Ramtron for Ferroelectric and Enhanced Static RAM Development.

Business Editors/High-Tech Writers

Nassda(TM) Corporation (Nasdaq:NSDA) today announced that Ramtron International Corporation (Nasdaq:RMTR) has adopted Nassda's HSIM(TM) hierarchical full-chip simulator and analysis tool for use in the development of Ramtron's memory technologies under a license agreement. Under the terms of the agreement, Nassda will license HSIM to Ramtron for use in development flows for all Ramtron products including Enhanced SRAM and ferroelectric random access memory (FRAM).

For this agreement, Nassda augmented HSIM with direct support for ferroelectric capacitor elements -- the ferroelectric crystals that lie at the core of Ramtron's next-generation FRAM memory technology. Prior to this enhancement, HSIM users had to model ferroelectric capacitors with redundant subcircuits that did not provide optimal performance. With direct support of transistor-level circuits containing ferroelectric capacitors, users gain the full advantage of HSIM's high capacity, accuracy and performance.

"Ramtron's patented FRAM products combine high-performance and low-power operation with the ability to retain data without power," said Craig Rhodine, Chief Operating Officer at Ramtron. "With the addition of ferroelectric crystal elements, Nassda's HSIM delivers the high speed, capacity and accuracy that we need to verify innovative FRAM designs for Ramtron and its foundry partners."

"As memory continues to grow proportionally in SoCs, we see new low-power, non-volatile technologies from innovative companies such as Ramtron becoming more prevalent," said Sang Wang, CEO of Nassda. "The addition of direct support for ferroelectric capacitors to HSIM demonstrates Nassda's commitment to continue addressing the industry's most challenging circuit verification requirements. We're pleased to be working with Ramtron in providing this capability for FRAM development."

About HSIM

HSIM provides detailed circuit-level analysis of timing and power behavior and signal integrity effects. It solves the critical issue of analyzing circuit behavior while taking into account the electrical and parasitic effects of nanometer-scale silicon. It is ideal for demanding analog, memory, mixed-signal and system-on-chip designs.
