  1. The Memristor

  2. 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.

  3. What Is It? • A type of electrical circuit. • The fourth mystery element that joins the capacitor, resistor, and inductor.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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. http://arstechnica.com/news.ars/post/20080501-maintaining-moores-law-with-new-memristor-circuits.html

  10. 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.

  11. 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.

  12. 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.

  13. 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.
