Nonvolatile F-RAM memory device

Ramtron International has launched the FM24L256, a 256Kb, 2.7 to 3.6V nonvolatile F-RAM memory device with a high speed serial I2C memory interface.

The FM24L256 has been designed to provide high performance data collection in an 8pin package, for applications such as multi function printers to industrial motor controllers. The FM24L256 is a 256Kb nonvolatile memory employing Ramtron's ferroelectric process. F-RAM memories read and write like RAM and provide reliable data retention for 10 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM24L256 performs write operations at bus speed without write delays and the next bus cycle can start immediately without the need for data polling. The device offers write endurance that is orders of magnitude higher than EEPROM and uses much lower power during writes than EEPROM, since write operations do not require an internally elevated power supply voltage for write circuits. The FM24L256 is suitable for users of serial EEPROM in a hardware drop in replacement. It is available in an 8pin SOIC package, operates from 2.7 to 3.6V volts, and is rated over the industrial temperature range of -40 to +85 ºC.
