Patent ID: 6977835

Claim:
A ferroelectric register, comprising: a pull-up switch for outputting a power voltage when a pull-up enable signal is activated; a pull-up driving unit for receiving the power voltage from the pull-up switch, and for pulling up a voltage of a data storage node to the power voltage; a write enable control unit for transmitting a differential data to the data storage node according to a write control signal; a ferroelectric capacitor unit including at least two ferroelectric capacitors connected in parallel between the data storage node and a plate line, and storing the differential data when a cell plate signal is activated; a pull-down switch for transmitting a ground voltage to the data storage node when a pull-down enable signal is activated; and a pull-down driving unit for receiving the ground voltage from the pull-down switch, and for pulling down the voltage of the data storage node to the ground voltage.
