Patent ID: 8217725

Claim:
An electrical circuit, comprising: a first path including even-number inverters connected in series from a first node serving as an input side to a second node serving as an output side; a second path including even-number inverters connected in series from the second node serving as an input side to the first node serving as an output side; a latch circuit providing a connection between the first node and the second node such that a logical value of the first node and a logical value of the second node are opposite to each other; and one or more control signal paths to supply one or more control signals to the latch circuit to provide and sever a connection between the latch circuit and a power supply, wherein the one or more control signals include: a first control signal output from a first inverter that is one of the even-number inverters of the first path, and a second control signal output from a second inverter that is one of the even-number inverters of the second path.
