Patent ID: 8374041

Claim:
A transfer circuit comprising: a first inverter which is provided with a function of turning on or off state and which inverts, when on state, data at a first node and transfers the inverted data to a second node; a second inverter which is provided with a function of turning on or off state and which inverts, when on state, the data at the second node and transfers the inverted data to the first node; a first signal line connected to the first node; a second signal line connected to the second node; a first holding circuit which may output data to the first node and which may hold data at the first node; and a second holding circuit which may output data to the second node and which may hold data at the second node, wherein when the first holding circuit outputs the data to the first signal line through the first node, the first and second inverters are turned off state, and when the second holding circuit outputs the data to the first signal line through the second node, the first inverter is turned off and the second inverter is turned on.
