What is ferroelectric memory?

Ferroelectric memory with random access (FRAM) stores computer data using a special "ferroelectric film" that has the ability to quickly change polarity. It is able to maintain data, even if the power is not on, so it is classified as an energy memory. Ferroelectric memory works without batteries and consumes low energy when the information is written or rewritten into a chip. The performance of random access memory is combined with memory only for read in ferroelectric memory. It is used for smart cards and mobile devices such as mobile phones because little energy is used and memory chips is difficult to access them that handles them. Atoms in the film change electric polarity to positive or negative, or vice versa. This causes the film to behave like a switch that is compatible with binary code and can allow data to be stored. The polarity of the film remains the same when the force is off, keeps the information intact and allows the chip to workWithout great energy. Ferroelectric Memory chips will even keep data if the power suddenly turns off, for example in a power outage.

Compared to dynamic memory with random access (DRAM) and electrically deceiving programmable memory only for reading (EEPROM), ferroelectric memory consumes 3,000 times less power. It is also estimated that it takes 10,000 times longer, because the information can be written, erased and rewritten many times. The dielectric layer is used in DRAM, but instead a ferroelectric layer is used. The structure of various memory chips is otherwise very similar.

also known as FERAM, ferroelectric memory can write much faster than other memories. The write speed is estimated to be almost 500 times faster than the EEPROM. Scientists used electron microscopes to create images of electrical fields on the memory chip surface. Using this technique they can measure materials,that allow polarization control on atomic scales to create memory chips that work even faster.

Ferroelectric memory is more energy efficient than other types of computer memory. It is also safer to use and store data, as important information is not so easy to lose. It is suitable for use on mobile phones and radio frequency identification systems. Memory chips can also rewrite data many times, so the memory will not wear and need to be replaced in a short time.
