Summary
Memristors are devices that maintain a relationship between the time integrals of current and voltage. This document explains what they are, how they work, and their potential uses in future memory devices.
Memristors and their properties
Memristors are two-terminal elements that vary in resistance according to their memristance function. They exhibit hysteresis and can access a 'history' of applied voltage. They are not purely memristors but also show some capacitance, resistance, and inductance.
Memristors as switches
Some memristors can act as switches, changing resistance greatly when current or voltage is applied. Their power characteristic differs from that of a metal oxide semiconductor transistor. They do not depend on bias voltage for their final state of charge.
Memristors' potential applications
Memristors could replace dynamic random access memory (D-RAM) and be used in crossbar latches to replace transistors. They could also enable computers to compute like human brains. They could be stacked in multiple layers on a single chip.
Memristors and the future of electronics
The semiconductor industry's focus on shrinking transistors will eventually end. Memristors are an example of a device that is increasingly capable, not just infinitesimal. They could replace multiple transistors and other passive elements in circuits.
Key terms
- Memristance
- The resistance of a memristor that varies according to its history of applied voltage.
- Hysteresis
- An accelerating rate of change as an object moves from one state to another.
- Dynamic random access memory (D-RAM)
- A type of computer memory that lacks the ability to retain information once power is turned off.
- Crossbar latches
- Devices that combine solid-state memristors and could replace transistors in future computers.
- Von Neumann architecture
- The architecture underpinning all digital computers, which memristor-based computers could differ from.
- Memcapacitors and meminductors
- Complementary circuits to the memristor which allow for the storage of charge.
