Introduction
ASIC Vs General Purpose IC
What Makes all this happen ? 
If { G is on} 
{ 
Current flows through 
D & S 
}
How Do We Build Them?
OLD 
VERSION
BIOS ROM CHIP 
• A program burned onto it 
• Knows where to look for, and how to access, the different expansion slots, 
ports, drives, and the Operating System.
Moore’s Law On April 19, 1965 Moore 
predicted the most important law ever 
proposed in Semiconductors. 
”number of transistors in a dense integrated 
circuit doubles approximately every two years.”
INTEL Processor’s Growth 
* All the predictions are based on wiki…could be approximate

Human – Computer Analogy 
Should We call 
It a processor or 
System on chip 
{SOC}?

WHAT LIES AHEAD ????
Bio Inspired Computations 
Brains demonstrate 
– massive parallelism (1011 neurons) 
– massive connectivity (1015 synapses) 
– excellent power efficiency 
• much better than today’s microchips 
– low-performance components (~ 100 Hz) 
– low-speed communication (~ metres/sec) 
– adaptivity 
– tolerant of component failure 
– autonomous learning
Flexible Electronics

CPH4 {code Name}-- a molecule that the pregnant woman is making it 
after six weeks of pregnancy in very, very tiny quantities.
