THINKING MACHINE MEMRISTOR
INTRODUCTION
Memristor is a contraction of “memory resistor,” because that is exactly its function: to remember its history.
A Memristor is a two-terminal device whose resistance depends on the magnitude and polarity of the voltage applied to it and the length of time that voltage has been applied.
WHAT IS IT?
The world’s smallest memristive switch.
-(50 x 50 nanometers)
Information storage device.
A concentration of memory resistors.
A passive two-terminal circuit elements that maintains a functional relationship between the time integrals of current and voltage.
HISTORY
Memristor theory was formulated and named by Leon Chua in a 1971 paper.
LEON CHUA'S THEORY
Leon Chua suspected that a memristor should exist based primarily on symmetry.
Resistor dv/di = R (ohms)
Capacitor dq/dv = C (farad)
Inductor dΦ/di = L (henry)
? dΦ/dq = ?
