Emerging memories

Which property does FeRAM (ferroelectric memory) use to store information?

  1. AFormation and dissolution of conductive filaments in an oxide
  2. BThe magnetoresistance effect
  3. CThe direction of spontaneous (remanent) polarization of a ferroelectric
Show answer and explanation

Answer: C. The direction of spontaneous (remanent) polarization of a ferroelectric

FeRAM is a non-volatile memory that uses a ferroelectric's property of retaining polarization after the voltage is removed (remanent polarization), storing 0 and 1 in the polarization direction. Conductive filaments are used by ReRAM, and the magnetoresistance effect by MRAM.
