Abstract:
A semiconductor logic element having a semiconductor substrate with an output electrode for issuing a high or low level voltage when a high or low level voltage is applied respectively to the first, second, third and fourth control electrodes, wherein:said first and third control electrodes are disposed adjacent to each other,said second control electrode is formed adjacent to said first and third control electrodes,said fourth control electrode is formed adjacent to said first and third control electrodes, and opposite the second control electrode relative to said first and third control electrodes, andsaid output electrode issues a voltage based on a first logic operation in response to a voltage applied to said first and second control electrodes, while a fixed low level voltage is applied to said second and fourth control electrodes, and said output electrode issues a voltage based on a second logic operation and differing from the first logic operation in response to a voltage applied to said first and third control electrodes, while a fixed high level voltage is applied to said second and fourth control electrodes.
