Ramtron starts shipping IBM made FRAM chips

Ramtron International Corporation has announced the broad sampling of the first pre-qualification ferroelectric random access memory (F-RAM) devices built on the company's new manufacturing line at IBM Corporation. The FM24C04C and FM24C16C are serial 5-volt devices with 4- and 16-kilobits of F-RAM memory, respectively.

"Releasing samples of the FM24C04C and FM24C16C devices is a significant milestone in our new foundry program," said Eric Balzer, Ramtron's CEO. "These pre-qualification devices, which meet all datasheet specifications and our stringent quality standards, are available now for customer evaluation. Additional devices, including 3-volt I2C and 3- and 5-volt SPI products, will become available for sampling as testing is completed."

The FM24C04C and FM24C16C feature a serial I2C interface, have an active current of 100µA (typical at 100kHz) and perform up to 1MHz bus frequency. The devices are direct drop-in replacements for 4- and 16-Kb serial EEPROM memories used in industrial controls, metering, medical, military, gaming, and computing applications, among others. The FM24C04C and FM24C16C are offered in an industry standard 8-pin SOIC package and operate over the industrial temperature range of -40°C to +85°C.

Ramtron's FM24CxxC products offer single-byte writes that are 200 times faster than those of EEPROM. In addition, the devices offer no timing delays and can be written to at standard bus speeds as compared to EEPROM, which requires a 5- to 10-millisecond write delay before new data can be registered. The FM24C04C and FM24C16C feature 1-trillion write cycles, compared to 1-million write cycles for EEPROM, and have an extremely low operating current compared to competing nonvolatile memory products.
