Ferroelectric memory (FRAM) is an interesting storage technique that stores bits in a special "ferroelectric" material. Ferroelectric memory is nonvolatile like flash memory, able to hold its data for decades. But, unlike flash, ferroelectric memory can write data rapidly. Moreover, FRAM is much more durable than flash and can be be written trillions of times. With these advantages, you might wonder why FRAM isn't more popular. The problem is that FRAM is much more expensive than flash, so it is only used in niche applications.
