MEMory ResISTOR+

Defination of Memristor A memristor is a semiconductor whose

resistance varies as a function of flux and current.

Characterized by Memristance

Concept of Memristance

Memristance is simply charge-dependent resistance.

Unit - ohm (Ω)

Symbol

Invention Of Memristic Theory

Theory was developed in 1971 by Professor Leon Chua.

HP Lab scientiests were first to observe the “memristive behavious”

Stanley Williams

In 2006, Stanley Williams developed practical model.

Fundamental Relationships

Property Of Memristor Retain its resistance level.

Recall the last resistance it had, before being shut off.

Benefits Of Memristor Technology

•Would allow for a quicker boot up

Benefits Of Memristor Technology Uses less energy and

produces less heat.

Can replace today’s commonly used Dynamic Random Access Memory

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

Benefits Of Memristor TechnologyCreating 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.
