Abstract
A semiconductor device is provided having an internal circuit in which input data is gated and supplied to the internal circuit according to an internal control signal generated within the semiconductor device. The semiconductor device has N number (N being two or greater integers) of data input terminals for inputting input data, and a test mode input terminal for inputting a test mode signal. An OR device is provided for obtaining a logical sum of the internal control signal and the test mode signal. The semiconductor device also has N number of gate circuits that are supplied with the input data applied to the N data input terminals, respectively. When an output of the OR device is active, those of the N gate circuits responsive to the output of the OR device pass the input data applied to the data input terminals. The internal circuit is supplied with outputs of the N gate circuits.
