As mentioned previously, microcontroller power consumption is a considerable barrier to developing a smarter, greener world. To demonstrate the overall system savings of FRAM, a comparison is needed to show what it is like to write the same amount of data in FRAM as users would today in Flash. When writing 13 kB of memory, Flash can take up to one second to write to this memory size while FRAM, shown in blue and writing at 1400 kBps, takes only 10 ms, a factor of 100 times faster. Not only does this translate into a huge increase in speed but it ultimately means less time spent actively writing to memory. It also translates into less time consuming valuable battery power. In this specific case, Flash consumes 2200 µA while FRAM consumes only 9 µA, or 1/250th the power. When writing to memory, the power savings are clear. However, many applications do not write to Flash all the time. In this case, FRAM is very comparable to SRAM in speed and memory consumption.
