Comparing Flash and FRAM devices against each other, both executing at the same clock speed but each writing to non volatile memory at a high speed. The FR59 FRAM device is writing at a speed >1 Mbps while the flash device is writing at its maximum speed of 13 kbps. A comparison of the active power on both devices shows that the FRAM device is less than half the power of the Flash device while writing at a speed that is 100 times faster. In the case where both devices are writing at the same speed the FRAM device is 250 times lower power than the flash device since the active duty cycle is a small fraction on FRAM and the device is able to spend most of the time in standby. Clearly FRAM is not only orders of magnitude faster, but can accomplish the task with much lower power than flash – a double advantage for applications that require quick response time, lower average power and limited peak power such as energy harvesters.
