F-RAM Memory (Nonvolatile Ferroelectric RAM)
Trusted Global Leadership for Instant Data Capture with F-RAM
Cypress Semiconductor offers a comprehensive portfolio of serial and parallel F-RAM (ferroelectric RAM) non-volatile memories to instantly capture and preserve critical data when power is interrupted. In mission-critical data-logging applications like a high-performance Programmable Logic Controller (PLC) on the factory floor requiring high reliability control and throughput, or a life-enhancing patient monitoring device implanted in the human body designing in a low-power, small footprint memory, Cypress’ F-RAMs offer instant non-volatility and virtually unlimited endurance without compromising on speed or energy-efficiency.
Excelon™ F-RAM – High Performance. High Reliability. Ultra-Low Power
Excelon™, Cypress’s next-generation F-RAM delivers the industry’s lowest-power mission-critical nonvolatile memory, by combining ultra-low-power operation with high-speed interfaces, instant nonvolatility and unlimited read/write cycle endurance. This makes Excelon™ the ideal data-logging memory for portable medical, wearable, IoT sensor, industrial and automotive applications.
Excelon™ offers up to 70x reduction in typical standby current compared to standard F-RAMs and a low-pin-count 108 MHz Quad SPI interface that is as fast as a parallel interface with 35ns burst access time. Excelon™ F-RAM supports 1.71V to 1.89V operating voltage range in addition to the wide-voltage 1.8V to 3.6V range and is now available in a small footprint 10mm2 8-pin GQFN package.
F-RAM Technology and Benefits
Cypress F-RAM is 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 Flash.
