History of VLSI

VLSI, Very Large Scale Integration

History of VLSI

Late 40s 
Transistor invented at Bell Labs


Late 50s 
First IC (JK-FF by Jack Kilby at TI)


Early 60s 
Small Scale Integration (SSI)     
10s of transistors on a chip


Late 60s 
Medium Scale Integratoin (MSI) 
100s of transistors on a chip


Early 70s 
Large Scale Integration (LSI) 
1000s of transistor on a chip


Early 80s 
VLSI 10,000s of transistors on a chip (later 100,000s & now 1,000,000s)

Ultra LSI is sometimes used for 1,000,000s
