What is meant by ALE is never tristated?

Tristate means three states viz. Logic 0, Logic 1 and high impedance states. In high impedance state, the pin neither connected to supply nor to ground. Hence impedance at this pin is very high with respect to supply as well as ground. Some pins of 8085 have three states. In high impedance state, this pin is disconnected from internal circuit of microprocessor electrically but not physically. In this state, the processor is disconnected from the bus.
