The memristor

The Memristor


What is it

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.


What is it1

What Is It?

  • A type of electrical circuit.

  • The fourth mystery element that joins the capacitor, resistor, and inductor.


Benefits of memristor

Benefits of Memristor

  • Provides greater resiliency and reliability when power is interrupted in data centers.

  • Have great data density.

  • Combines the jobs of working memory and hard drives into one tiny device.

  • Faster and less expensive than MRAM.


Benefits of memristor1

Benefits of Memristor

  • Uses less energy and produces less heat.

  • Would allow for a quicker boot up since information is not lost when the device is turned off.

  • Operating outside of 0s and 1s allows it to imitate brain functions.

    • Eliminates the need to write computer programs that replicate small parts of the brain.


Benefits of memristor2

Benefits of Memristor

  • Creating a Computer that never has to boot up.

  • Does not lose information when turned off.

  • Density allows for more information to be stored.

  • Has the capacity to remember the charge that flows through it at a given point in time.


What sets memristor apart

What Sets Memristor Apart?

  • Conventional devices use only 0 and 1; Memristor can use anything between 0 and 1 (0.3, 0.8, 0.5, etc.)

  • Faster than Flash memory.

    • Allow digital cameras to take pictures with no delay inbetween.

  • Innovating nanotechnology due to the fact that it performs better the smaller it becomes.


What sets memristor apart1

What Sets Memristor Apart?

  • By changing the speed and strength of the current, it is possible to change the behavior of the device.

  • A fast and hard current causes it to act as a digital device.

  • A soft and slow current causes it to act as an analog device.


Future technological significance

Future Technological Significance

  • Hope to one day have a computer that processes information in the same way as the human brain.

    • Gaining control over the device could lead to computers that actually learn.

Future technological significance1

Future Technological Significance

  • Development of nonvolatile memory with a memristor base.

    • HP is currently focusing on this possibility.

    • Use less power.

    • More magnetic than magnetic disks.

  • Could lead to the replacement of the transistor.

  • Appliances that “learn” from experiences.


Future technological significance2

Future Technological Significance

  • Could be put in cell phones as monitoring devices to track pollution and other things in the environment.

  • Used in common devices for unbelievable storage.

    • Camera can take days worth of video with storage the size of an average thumb drive.


Key terms

Key Terms

  • Resistor - a two-terminal electronic component designed to oppose an electric current by producing a voltage drop between its terminals in proportion to the current.

  • Inductor-a passive electrical component with significant inductance

  • Capacitor- an electronic device that can store energy in the electric field between a pair of conductors.


Key terms1

Key Terms

  • Nanotechnology- a field of applied science whose theme is the control of matter on an atomic and molecular scale.

  • MRAM- ( Magnetoresistive Random Access Memory ) a non-volatile computer memory technology.
