What Role Does Hafnium Oxide Play in Memory Devices?
Hafnium oxide is also utilized in the fabrication of non-volatile memory devices such as Resistive Random-Access Memory (ReRAM) and Ferroelectric Random-Access Memory (FeRAM). In ReRAM, HfO2 acts as the switching layer where resistance change occurs due to the formation and rupture of conductive filaments. In FeRAM, doped HfO2 exhibits ferroelectric properties that enable data storage through polarization states.
