Ferroelectric RAM is a random-access memory similar in construction to DRAM but using a ferroelectric layer instead of a dielectric layer to achieve non-volatility.

How does FRAM memory work?

The FRAM memory cell operates by applying a switched voltage to sense and restore the data state. The ferroelectric film PZT is about 70nm thick. If the device is placed in a 50 kV field at 1 cm, it is not possible to produce more than 1V across the ferroelectric film.

What are the unique characteristics of FRAM?

What are the unique characteristics of FRAM? FRAM has the characteristics of both ROM (Read Only Memory) and RAM (Random Access Memory), and features faster write, great read/write cycle endurance, and low power consumption.
