MEMRISTOR
INTRODUCTION

GENERALLY WHEN PEOPLE THINK ABOUT
ELECTERONICS,THEY MAY INITIALLY THINK OF
PRODUCTS SUCH AS
PHONE,RADIOS,LAPTOPS,COMPUTERS ETC..

OTHERS HAVING SOME ELECTRONICS
BACKGROUND, MAY THINK OF
RESISTORS,CAPACITORS,ETC..

THEY ARE THE BASIC COMPONENTS NECESSARY
FOR ELECTRONICS FUNCTION.

MEMRISTOR THEORY WAS FORMULATED AND
NAMED BY LEON CHUA IN A 1971 PAPER

HE STRONGLY BELIEVED THAT A FOURTH DEVICE
EXISTED TO PROVIDE CONCEPTUAL SYMMETRY
WITH THE RESISTOR,INDUCTOR AND CAPACITOR

THIS SYMMETRY FOLLOWS FROM THE
DESCRIPTION OF BASIC PASSIVE CIRCUIT
ELEMENTS AS DEFINED BY A RELATION BETWEEN
TWO OF THE FOUR FUNDAMENTAL CIRCUIT
VARIABLES

THE REASON THAT THE MEMRISTOR IS
RADICALLY DIFFERENT FROM THE OTHER
FUNDAMENTAL CIRCUIT ELEMENTS IS
THAT,UNLIKE THEM IT CARRIES A MEMORY OF ITS
PAST

WHEN YOU TURN OFF THE VOLTAGE TO THE
CIRCUIT,THE MEMRISTOR STILL REMEMBER HOW
MUCH WAS APPLIED BEFORE AND FOR HOW LONG

THAT’S AN EFFECT THAT CAN’T BE DUPLICATED
BY ANY CIRCUIT COMBINATION OF
RESISTORS,CAPACITORS,INDUCTORS

THAT IS WHY MEMRISTOR IS QUALIFIED AS A
FUNDAMENTAL CIRCUIT ELEMENT.

THE ARRANGEMENT OF THESE FEW
FUNDAMENTAL CIRCUIT COMPONENT FORM
THE SASIS OF ALMOST ALL OF THE
ELECTRONIC DEVICES WE USE IN OUR DAILY
LIFE.
