Enabling Technology
Cheap/fast fuse connections
- small area (can fit lots of them)
- low resistance wires (fast even if in multiple segments)
- very high resistance when not connected
- small capacitance (wires can be longer)
Pass transistors (switches)
- used to connect wires
- bi-directional
Multiplexors
- used to connect one of a set of possible sources to input
- can be used to implement logic functions
