Advanced non-volatile memories
What is FeRAM?
Memories are electronic components used for the temporary storage of data. There are two main categories of memories, stand-alone (e.g. USB key) and embedded memories. Nowadays, embedded solutions are gaining much interest and non-volatile memories appear as the prime choice. In fact, their ability to retain data, even when deprived of power supply, make them critical for many applications.
There are different categories of non-volatile memories. One of them is FeRAM —Ferroelectric Random Access Memory. FeRAMs provide key advantages:
CEA-Leti can help industrial partners replace current, standard non-volatile memories with FeRAMs for several applications, including:
In the longer term, CEA-Leti can also help the following business segments migrate to FeRAMs:
Current FeRAMs are based on PZT material. However, these technologies have two drawbacks:
To make sure FeRAMs operate at their full potential, CEA-Leti introduced a new material called HfO2—hafnium oxide. HfO2 is changing the FeRAM paradigm by offering:
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
