256 Kb serial F-RAM

15 April 2009 DSP, Micros & Memory

Ramtron recently announced the FM24L256, a 256 Kb, 2,7 to 3,6 V nonvolatile F-RAM memory device with a high-speed serial I²C memory interface. The IC provides high-performance data collection in a tiny, 8-pin package, cutting costs and board space in a range of applications from multifunction printers to industrial motor controllers.

The FM24L256 is a 256 Kb nonvolatile memory employing Ramtron’s advanced 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 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.
