When a junction transistor used as a switch in a digital circuit is turned on as hard as it will go it is said to be saturated. In this condition there is excess charge in the collector region, and this has to drain away before the transistor will switch off again. This limits the speed at which it can switch, and so saturation is a condition designers try to avoid.
