Abstract
A semi-conductor decoder circuit includes 2.sup.N-1 circuits each formed of transistors vertically arranged in N stages, with the transistors of 2.sup.N-1, 2.sup.N-2 . . . 2.sup.1, 2.sup.0 number being disposed sequentially from the output stage in N stages in a tree structure. The gate width of the transistor at each stage is expanded as a distance from the output stage is increased so as to prevent an increase in ON resistance of the circuit and also to achieve a high speed operation.
