IC Evolution
SSI – Small Scale Integration (early 1970s)
contained 1 – 10 logic gates
MSI – Medium Scale Integration
logic functions, counters
LSI – Large Scale Integration
first microprocessors on the chip
VLSI – Very Large Scale Integration
now offers 64-bit microprocessors, complete with cache memory (L1 and often L2), floating-point arithmetic unit(s), etc.
Transistor Switch Model
NFET or n transistor
on when gate H
"good" switch for logic L
"poor" switch for logic H
"pull-down" device
PFET or p transistor
on when gate L
"good" switch for logic H
"poor" switch for logic L
"pull-up" device
