The Instant-On Green Computer

MemristorWe’ve had resistors, capacitors, and inductors as the three fundamental elements in circuits. Now we may finally have the physical manifestation of the "memristor," originally described back in 1971 by engineering student Leon Chua, thanks to nanotechnology and HP Labs. Basically, it’s a resistor with memory. As you might guess, this could lead to RAM that is non-volatile, and could power back on in the exact state it was when it was powered off. It could also mean much more energy efficient computers, since memory could remember it’s state without power. And these are just two of the major changes it could bring about…

  1. resistors, capacitors, and inductors are the heart,lungs,liver and brain of an electronic divice.
