| 摘要 |
A semiconductor device includes first, second and third terminals respectively receiving first, second and third input signals from outside, first, second and third input buffers respectively coupled to the first, second and third terminals, the first, second and third input buffers producing first, second and third buffered signals responsive to the first, second and third input signals, respectively, and first and second gate circuits respectively coupled to the first and second input buffers, the first and second gate circuits coupled to the third input buffer in common, the first and second gate circuits respectively driving output nodes thereof in response to the first and second buffered signals when the third buffered signal is activated, and each of the first and second gate circuits holding the output nodes thereof at a fixed level irrelatively to the first and second buffered signals when the third buffered signal is inactivated.
