How many read and write cycles does Fram have?
Flash technology has a limited write/erase cycles, but the reading cycles are almost unlimited. In FRAM, each read cycle actually affects the memory and it starts to degrade. TI states that they’ve found the FRAM has “Wear-out free endurance to 5.4 × 10^13 cycles and data retention equivalent of 10 years at 85°C”.
What’s the difference between Fram and flash memory?
FRAM is great, however, the technology has destructive reads. Flash technology has a limited write/erase cycles, but the reading cycles are almost unlimited. In FRAM, each read cycle actually affects the memory and it starts to degrade.
