Ramtron Unveils Industry's First 0.35 Micron FRAM

8/6/2003 - Ramtron International Corporation (Nasdaq:RMTR), a leading supplier of specialty semiconductor memory products, introduced and began sampling the first FRAM (ferroelectric random access memory) built using 0.35-micron design rules. The FM25CL04 is a 4-kilobit SPI interface nonvolatile RAM that operates at 3 volts and runs up to 20 MHz, providing fast data access and simplifying the interface to high-performance processors. When combined with FRAM’s virtually unlimited write endurance, the FM25CL04 is an ideal data storage memory.

The FM25CL04 is best suited for two categories of systems: First, applications operating from batteries or limited power sources benefit from its extremely low power operation; second, applications needing frequent or rapid writes such as office equipment and automotive applications benefit from the speed and high endurance.

“The 0.35 lithography of the FM25CL04 exhibits ferroelectric’s ability to scale effectively,” said Mike Alwais, vice president of FRAM products. “This new process enables Ramtron to develop highly integrated products in smaller packages, which increases functionality and value for our customers.”

Ramtron’s new 0.35-micron manufacturing process reduces the operating power and increases the die leverage per wafer compared to earlier generations of Ramtron’s FRAM products built on the company’s existing 0.5-micron manufacturing line.

Product Features and Benefits
The FM25CL04 provides an industry-standard SPI interface to access 4Kb of nonvolatile RAM. The product reads and writes continuously at bus speeds of up to 20 MHz with no write delays. Similar EEPROM devices require long millisecond write delays, write polling software, and have endurance limited to less than 1-million write cycles. The FM25CL04 operates from a 3-volt power supply and draws under 75 microamps for reads and writes at 100 kHz. It offers 10 years of data retention and is rated over the industrial temperature range of –40C to +85C.

Pricing and Availability
Samples of the FM25CL04 are available immediately in 8-pin SOIC packaging. Pricing starts at $0.59 in 10K quantities.

About the 0.35 Micron FRAM Technology
Advances in ferroelectric processing have enabled commercial FRAM products using 0.35-micron geometries. The FM25CL04 represents the first advanced nonvolatile memory produced on one of the most widely used semiconductor process nodes. In addition to standard memories, 0.35-micron geometries are suitable for high integration mixed-signal devices.

About Ramtron
Ramtron develops and markets patented FRAM memories, a new generation of semiconductor memory that combines high-performance and low-power operation with the ability to store data in the absence of power. Due to the product’s unique advantages, FRAM memories are expected to revolutionize a variety of electronic consumer and industrial designs.
