ABSTRACT:
The data coincidence detecting circuit detects the coincidence of first data having bits with second data having bits. The data conincidence detecting circuit includes input lines, with the bits of the first data being supplied to respectively, a first storing circuit having first storing elements to store the bits of the first data therein and a second storing circuit having second storing elements to store the bits of the second data therein. The first element has first and second terminals and an input terminal connected to the input line through a node. The second element has first and second terminals and is connected to the first element. The first and second elements have a function for electrically connecting between the first and second terminals when the stored bit is a first state and disconnecting between the first and second terminals when the stored bit is a second state. The data coincidence detecting circuit further comprises a first power supplying circuit connected to the first storing circuit to selectively supply a first electric potential and a second electric potential, a second power supplying circuit connected to the second data storing circuit to selectively supply the first potential and the second potential, a detecting circuit to detect the electric potential of the nodes and to output a detecting signal on an output terminal thereof and an output circuit connected to the output terminal of the detecting circuit to decide the coincidence of the first data and the second data by the detecting signal.
