This document provides an agenda for a seminar on memristors. It begins with an introduction defining memristors as semiconductors whose resistance varies as a function of flux and current. It then covers the invention of memristic theory in 1971, properties of memristors such as retaining resistance levels, working principles showing how applied voltage shifts oxygen vacancies, benefits such as lower power consumption and compatibility with CMOS technology, and potential future applications of memristor technology.

5. Defination of
Memristor
 A memristor is a semiconductor whose
resistance varies as a function of flux and
current.
 Characterized by Memristance

6. Concept of
Memristance
 Memristance is simply charge-dependent
resistance.
Unit - ohm (Ω)
Symbol

7. Invention Of Memristic
Theory
Theory was developed in 1971 by Professor
Leon Chua.
HP Lab scientiests were first to observe the
“memristive behavious”

8. Stanley
Williams
 In 2006, Stanley Williams developed
practical model.

9. Relationships

12. Property Of
Memristor
 Retain its resistance level.
 Recall the last resistance it had, before
being shut off.

 Applied voltage makes the oxygen vacancies
(+ve) to shift towards the –ve voltage.

14. Analogy Of Memristor
A RESISTOR WITH MEMORY
BEHAVES LIKE A PIPE

15. Benefits Of Memristor
Technology

•Would allow for a
quicker boot up

16. Benefits Of Memristor
Technology
 Uses less energy and
produces less heat.
Can replace today’s
commonly used
Dynamic Random
Access Memory

17. Benefits Of Memristor
Technology
 Compatible with CMOS technology.
 Power Consumption.
 Behaviour
 3 Memristors to make a NAND gate
 27 NAND gates to make a Memristor

18. Benefits Of Memristor
Technology
Creating a Analog Computer that
works much faster than Digital ones.
 Provides greater reliability when power
is interrupted in data centers.
Density allows for more information
to be stored.
