Patent ID: 6898107

Claim:
A nonvolatile FeRAM control device, comprising: a pumping voltage controller configured to output a pumping voltage control signal by receiving a power voltage control signal having a different output level according as a power voltage region where a power voltage belongs, when the power control signal is applied; a cell plate voltage controller configured to selectively output a cell plate pumping voltage control signal depending on states of the power voltage control signal, when a cell plate control signal is applied; a write enable voltage controller configured to selectively output a write enable pumping voltage control signal depending on states of the power voltage control signal, when a write enable control signal is applied; and a register array including a plurality of unit registers configured to boost and output voltage levels of data stored in a nonvolatile ferroelectric capacitor depending on voltage levels of the pumping voltage control signal, the cell plate pumping voltage control signal and the write enable pumping voltage control signal.
