1FRAM is non-volatile and can easily be read/written 10 trillion times. 2It's similar to Dynamic random-access memory (DRAM), only with a ferroelectric layer instead of a dielectric layer. 3It is particularly suitable for use with low power data loggers and for buffering data in the absence of a stable voltage source. 4The FRAM chip used provides 8 KB of memory, and USES a clock up to 20 MHz. 5Each byte can be read and written instantaneously, but will keep the memory for 95 years at room temperature.
