1. A semiconductor apparatus comprising:
- a decoder arranged in a path between a first power supply line and a second power supply line and configured to receive a signal and decode the signal;
a switch portion arranged, in series with said decoder, in the path between the first power supply line and the second power supply line; and
a control unit configured to set said switch portion in a conductive state so as to cause said decoder to decode the signal after the signal has changed from one of high level and low level to the other,wherein said decoder comprises at least two transistors arranged in series in the path between the first power supply line and the second power supply line.

10. A semiconductor apparatus comprising:
-
a decoder arranged in a path between a first power supply line and a second power supply line and configured to receive a signal and decode the signal, said decoder including a switch portion and decoding the signal received when said switch portion is in a conductive state; and a control unit configured to set said switch portion in the conductive state so as to cause said decoder to decode the signal after the signal has changed from one of high level and low level to the other, wherein said decoder comprises; a first transistor and a second transistor arranged in series in a first path between the first power supply line and the second power supply line; and a third transistor and a fourth transistor arranged in series in a second path between the first power supply line and the second power supply line, a first signal and a second signal whose signal level is opposite to the signal level of the first signal are input to said decoder, said first transistor and said fourth transistor operate upon receiving the first signal, and said second transistor and said third transistor operate upon receiving the second signal. - View Dependent Claims (11, 12, 13)

14. A semiconductor apparatus comprising:
-
a first transistor and a second transistor arranged in series in a first path between a first power supply line and a second power supply line; and a third transistor and a fourth transistor arranged in series in a second path between the first power supply line and the second power supply line, wherein when said first transistor and said fourth transistor receive a first signal, and said second transistor and said third transistor receive a second signal whose signal level is opposite to the signal level of the first signal, said first transistor, said second transistor, said third transistor, and said fourth transistor output signals corresponding to the first signal and the second signal, said semiconductor apparatus further comprises; a switch portion arranged in each of the first path and the second path; and a control unit configured to set said switch portion in a conductive state so as to cause said first transistor, said second transistor, said third transistor, and said fourth transistor to output the signals corresponding to the first signal and the second signal after each of the first signal and the second signal has changed from one of high level and low level to the other. - View Dependent Claims (15, 16, 17)
