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.
