TLDR
In this paper, a data hold and data output method for nonvolatile flip-flop circuits is proposed, in which the application of the data signal is cut off and the ferroelectric polarization of a gate transistor is maintained, so that output signals Q(-Q) are outputted based on the held data signal (D).Abstract:
A method for driving a nonvolatile flip-flop circuit, comprising a data hold step in which a first clocked inverter (604), a second clocked inverter (603) and a third switching element (602) are on-state, a first switching element (605), a second switching element (607) and a third clocked inverter (608) are off-state, and a data signal (D) is inputted, whereby the ferroelectric polarization of a ferroelectric gate transistor (601) is utilized to hold the input data signal (D); and a data output step in which the first clocked inverter (604), the second clocked inverter (603) and the third switching element (602) are turned off, the first switching element (605), the second switching element (607) and the third clocked inverter (608) are turned on, whereby the application of the data signal (D) is cut off and the ferroelectric polarization of the ferroelectric gate transistor (601) is maintained, so that output signals Q(-Q) are outputted based on the held data signal (D).read more
