Question

Ultra Large Scale Integration are used in fabrication of

(a) 8-bit microprocessors, RAM, ROM

(b) 16 and 32- bit microprocessors

(c) Special processors and Smart sensors

(d) All of the mentioned

The question was posed to me by my school principal while I was bunking the class.

My question is from IC Chip Size and Circuit Complexity topic in section IC Fabrication of Linear Integrated Circuits

Answer 1

Correct choice is (c) Special processors and Smart sensors

Break it down: Ultra Large Scale Integration have nearly 10^6 – 10^7 transistors/chip. Hence, it is possible to fabricate smart sensors and special processor.
