Abstract
Herein disclosed is a semiconductor integrated circuit device which includes a unit cell for forming such an input/output circuit portion as is made capable of selecting any of a plurality of different input and output functions by changing a wiring pattern. The semiconductor integrated circuit is constructed such that there are formed in a manner to correspond to the unit cell a plurality of bonding pad regions which can be separated from one another so that any of the plural input and output functions can be arbitrarily selected through those bonding pad regions.
