Ramtron Samples 64-Kilobit Serial F-RAM Memory

Newest Device Completes Sampling of 5-Volt I2C Serial Family Built on New Manufacturing Line

COLORADO SPRINGS, CO - Ramtron International Corporation (Nasdaq: RMTR), a leading developer and supplier of ferroelectric-based low-power memory and integrated semiconductor products, today announced broad sampling of its newest ferroelectric random access memory (F-RAM) product built on the company's manufacturing line at IBM Corporation (NYSE: IBM). The FM24C64C is a 64-Kilobit (Kb), 5-volt serial F-RAM device that performs at bus speed without write delays, and supports up to one-trillion (1e12) read/write cycles - a million times more than a comparable EEPROM device. The FM24C64C offers low power operation with 100 µA active current (at 100 kHz) and only 4 µA typical standby current. This F-RAM device is a direct hardware replacement for 64-Kb EEPROM and is ideal for nonvolatile memory applications that require frequent or rapid writes.

"The FM24C64C expands our family of low-density serial I2C devices manufactured on our IBM manufacturing line in Burlington, Vermont," comments Ramtron marketing manager, Mike Peters. "The FM24xxC line of products includes 4-Kb, 16-Kb and 64-Kb serial devices with an I2C interface. Ramtron's F-RAM products offer superior write performance, endurance and retention over competing devices."

About the FM24C64C

The FM24C64C features a serial I2C interface, has an active current of 100 µA (typical at 100 kHz), and performs up to 1MHz bus frequency. The device is a direct drop-in replacement for 64-Kb serial EEPROM and is frequently used in industrial controls, metering, medical, military, gaming, and computing applications, among others. The FM24C64C is offered in an industry standard, RoHS compliant 8-pin SOIC package and operates over the industrial temperature range of -40°C to +85°C.

About Ramtron and F-RAM Technology

Ramtron International Corporation, headquartered in Colorado Springs, Colorado, is a fabless semiconductor company that designs, develops and markets specialized semiconductor memory and integrated semiconductor solutions used in a wide range of product applications and markets worldwide.

Ramtron pioneered the integration of ferroelectric materials into semiconductor products that enabled a new class of nonvolatile memory, called ferroelectric random access memory, or F-RAM. Ramtron's ferroelectric memories combine high-speed performance of Random Access Memory (RAM) with true nonvolatile storage that delivers the ability to save data without power. Since commercializing the technology, Ramtron has sold nearly a half-billion F-RAM devices into demanding applications such as automotive safety and entertainment systems, portable medical devices, industrial process control systems, smart electricity meters, and consumer printer cartridges. As the most power-efficient of any nonvolatile memory technology on the market, F-RAM products promise to pave the way for the development of ultra-efficient battery powered products and energy harvesting applications, among others.
