RAM memory that almost doesn't consume electricity

RAM memory that almost doesn't consume electricity

RAM memory is another great source of electric consumption, even if it doesn't seem so individually. The problems arise, as always, when thousand million devices are taken into account. There's an interesting development in this field that avoids the use of electricity for keeping the memory active. Conventional RAM memory needs energy because without it, it loses its contents.


And that's where a new type of RAM solves this problem and provides other benefits. It's called ferroelectric RAM, and it uses a material of this kind instead of dielectric layer. Using the properties of ferroelectric materials, once the data are sent to the memory, they stay without the need of a single electron more.

It was proposed initially by a MIT student, far away in 1952. Since then, some research are being done by very well known companies and several do use FeRAM.


Other benefits of FeRAM:

  • Great tamper prevention.

  • Endurance and reliability.

  • Speed enough for microcontrollers.
