<P>PROBLEM TO BE SOLVED: To provide a semiconductor device capable of operating at high speed and reducing power consumption. <P>SOLUTION: A semiconductor device includes a latch circuit comprising: a level shifter: a first buffer and a second buffer; a first switch and a second switch; and a first terminal, a second terminal receiving the input of an inversion signal of a signal input from the first terminal, and a third terminal receiving the input of a clock signal that controls the states of the first switch and the second switch. A first output terminal of the level shifter is connected to one input terminals of the first buffer and the second buffer via the first switch. A second output terminal of the level shifter is connected to other input terminals of the first buffer and the second buffer via the second switch. A first input terminal of the level shifter is connected to an output terminal of the first buffer, and a second input terminal of the level shifter is connected to an output terminal of the second buffer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
