Serial FRAM Nonvolatile Memory Devices

Infineon Technologies Serial F-RAM (ferroelectric RAM) memories combine the nonvolatile data storage capability of ROM with the fast speeds of RAM. Serial F-RAM features a variety of interface and density options, including SPI and I2C interfaces, industry-standard packages, and densities ranging from 4KB to 4MB. Infineon Serial F-RAMs have three distinct advantages over other nonvolatile memory technologies: fast write speed, extremely high endurance, and low power consumption. Serial F-RAMs provide 100 trillion cycle endurance, exceeding the 1 million write cycle limitation of EEPROM. This eliminates the need for wear leveling to support a product over its lifespan.
