Ramtron Samples High-Speed Serial F-RAM Devices
New F-RAM Memory Family Offers Serial Peripheral Interface for Demanding Industrial Controls
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 pre-qualification sampling of a new family of 4- to 64-Kilobit (Kb) serial nonvolatile ferroelectric RAM (F-RAM) products. Produced on Ramtron's ferroelectric memory process at its new U.S. wafer source, the new products feature 1-trillion (1e12) read/write cycles, low power consumption, and NoDelay(TM) writes.
The FM25040C, FM25C160C, and FM25640C are 4-, 16-, and 64-Kilobit (Kb) memory devices that perform write operations at bus speeds of up to 20MHz with an industry standard Serial Peripheral Interface (SPI). Data is written to the F-RAM memory array immediately after it is received by the device. Unlike EEPROM and other nonvolatile memories that require data polling, F-RAM allows the next bus cycle to commence immediately. These characteristics make Ramtron's latest serial F-RAM devices an ideal nonvolatile memory for applications that require frequent and rapid writes, such as industrial controls and high-speed data logging.
About the FM25xxxC Family
The devices in Ramtron's FM25xxxC family feature a serial SPI interface and operate at 5-volts over the complete industrial temperature range of -40°C to +85°C. In addition, the products offer low power consumption with 250 µA active current (typical at 1 MHz clock speed) as well as a sophisticated write protection scheme that prevents inadvertent data writes to the memory. All of the devices are offered in an industry standard 8-pin "Green," RoHS-compliant SOIC package.
In addition to the FM25xxxC family, Ramtron is also sampling a family of FM24xxxC products, which includes 4-Kb, 16-Kb, and 64-Kb serial devices with an I2C interface.
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 hundreds of millions of 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.
