Emerging memories

What does the "Fe" in FeRAM stand for?

  1. ABeing fast
  2. BUsing a ferroelectric material
  3. CUsing iron (chemical symbol Fe) in the storage layer
Show answer and explanation

Answer: B. Using a ferroelectric material

The "Fe" in FeRAM stands for ferroelectric; it uses the property of ferroelectric materials whose polarization remains after the voltage is removed. Despite the letters Fe, it does not mean the memory uses iron.

  • A. It is not an abbreviation for speed.
  • B. Correct. It is memory that uses a ferroelectric material.
  • C. It does not refer to the element iron.
