F-RAM (Ferroelectric RAM)
Highly reliable, low power data logging memory
F-RAM (Ferroelectric RAM) サブカテゴリー
FRAM (Ferroelectric Random Access Memory or FeRAM) is a stand-alone nonvolatile memory that enables you to instantly capture and preserve critical data when power is interrupted. They are ideal for mission-critical data-logging applications like high-performance Programmable Logic Controllers (PLC) requiring high reliability control and throughput, or life-enhancing patient monitoring devices. Designed in a low-power, small footprint, F-RAMs offer instant non-volatility and virtually unlimited endurance without compromising on speed or energy-efficiency.
Density: 4Kb, 16Kb, 64Kb, 128Kb, 256Kb, 512Kb, 1Mb, 2Mb, 4Mb, 8Mb, 16Mb
Interface: I2C, SPI, QSPI, Parallel(X8, X16)

F-RAM memories are built on Ferroelectric technology. The F-RAM chip contains a thin ferroelectric film of lead zirconate titanate, commonly referred to as PZT. The atoms in the PZT change polarity in an electric field, thereby producing a power efficient binary switch. However, the most important aspect of the PZT is that it is not affected by power disruption, making F-RAM a reliable nonvolatile memory. The underlying operation principle of the F-RAM and its unique memory cell architecture imparts specific advantages that sets the technology apart from competing memory technologies like EEPROM or NOR Flash.
F-RAM products are among the industry’s lowest power nonvolatile memory solutions consuming much lesser active currents than competing EEPROM and MRAM solutions. This makes F-RAMs suitable for battery operated devices such as wearables and medical implants. Virtually unlimited endurance and instant non-volatility ensure that F-RAMs outperform existing memories like EEPROM and NOR Flash in several datalogging applications.
