UPSC Notes & Key Pointers

  • A memristor is a two-terminal electronic device whose resistance depends on its previous electrical state.

  • The term combines memory + resistor.

  • It was proposed theoretically by Leon Chua in 1971.

  • Memristors can retain information about past electrical signals.

  • They have potential applications in non-volatile memory, neuromorphic computing and artificial intelligence hardware.
