Fujitsu Semiconductor FRAM (Ferroelectric Random Access Memory)

Fujitsu Semiconductor FRAM (Ferroelectric Random Access Memory) is a non-volatile memory featuring fast writing speed operation, high read/write endurance and low power consumption. These features make FRAM ideal for applications requiring continuous data logging, real-time recording of three-dimensional position information, and data protection from sudden power outages.

Fujitsu Semiconductor FRAM is offered in serial (SPI and I2C interfaces) and parallel (parallel interface) variants and in a wide range of compact, high-density package types. Memory size options are available from 4Kbit up to 8Mbit.
