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
