F-RAM (Ferroelectric RAM) memory solutions for critical data logging
F-RAM (Ferroelectric Random Access Memory or FeRAM) is a standalone non-volatile 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: 4 Kb, 16 Kb, 64 Kb, 128 Kb, 256 Kb, 512 Kb, 1 Mb, 2 Mb, 4 Mb, 8 Mb, and 16 Mb
Interface: I2C, SPI, QSPI, and parallel (X8, X16)

Highly-reliable nonvolatile memory enabled by ferroelectric technology
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 PZT change polarity in an electric field, thereby producing a power-efficient binary switch. However, the most important aspect of PZT is that it is not affected by power disruption, making F-RAM a reliable non-volatile memory. The underlying operation principle of F-RAM and its unique memory cell architecture impart specific advantages that set the technology apart from competing memory technologies like EEPROM or NOR flash.
