Driving method of the nonvolatile flip-flop circuit using a resistance change element

摘要

In the nonvolatile flip-flop circuit connected to the resistance variable element first, the second through the control transistor to the storage node first flip-flop circuit, the second store step, the resistance change of the first and second After the low resistance both elements of the resistance variable element in the first and second, while maintaining the low resistance variable resistance element is connected to a storage node that stores a "0" and "1" The high resistance of only the variable resistance element is connected to a storage node that stores "1", connected to the variable resistance element is a low resistance to the storage node recall step, is connected to the variable resistance element is a high resistance driving method of a nonvolatile flip-flop circuit for sequentially to remember a "0" to the storage node that is
