Ferroelectric field effect transistor (FeMFET) for multi-bit per cell memories and in-memory computing applications
The recent discovery of ferroelectricity in hafnium oxide (HfO2) thin films generates a strong interest for ultra-low power non volatile memories, in which the information is stored by the orientation of the electric dipoles in this material. Among those memories, the ferroelectric field effect transistor (FeFET) is quite appealing to combine logic and memory operations […] >>
