摘要： A nonvolatile memory device comprises a plate line driving circuit having a hierarchical word line structure. The plate line driving circuit is coupled to plate lines corresponding to a main word line. The plate line driving circuit transmits a plate line drive signal to the plate lines when the main word line is selected, and connects the plate lines to the main word line when the main word line is unselected. Therefore, a floating condition in the plate lines when the main word line is unselected can be prevented.

摘要： A ferroelectric random access memory device including a pulse generator circuit capable of generating a pulse signal in response to an address transition. A chip enable buffer circuit activates a chip enable flag signal in response to a first transition of the pulse signal. A row selector circuit selects and drives one of the rows in response to the address. The row selector circuit also generates a flag signal indicating a selection of a plate line. A control circuit activates a plate control signal in response to the activation of a write enable signal, and deactivates the plate control signal in response to a second transition of the pulse signal. A plate line of a selected row is re-activated according to activation of the plate control signal and is deactivated according to deactivation of the plate control signal.

摘要： A ferroelectric random access memory device of the present invention includes an access transistor having a gate connected to a word line and a current path connected between a bit line and an internal cell node. A ferroelectric capacitor is connected between the internal cell node and a plate line. A reference voltage generator for generating a reference voltage includes a linear paraelectric capacitor. Data stored in the ferroelectric capacitor is sensed by activating the word line so as to connect the ferroelectric capacitor to the bit line. The plate line is then activated and simultaneously the reference capacitor is connected to a complementary bit line. After a voltage difference between the bit line and the complementary bit line is detected, the reference capacitor is insulated from the complementary bit line.

摘要： A reference circuit, which is applied to a ferroelectric random access memory device, includes a polarization state detection circuit having dummy cells with ferroelectric capacitors. The detection circuit checks polarization states of the ferroelectric capacitor in the dummy cells using dumping voltages of different levels, and generates pass/fail signals as a check result. The generated pass/fail signals are decoded, using themselves as selection information for selecting one of reference voltages, of different levels, which are generated from a reference voltage generation circuit. Thus, it is possible to generate an optimal reference voltage, which senses a ferroelectric capacitor polarization state that is changed with time.
