The redundancy circuit comprises an address buffer for outputting a first internal address and a second internal address (used only during redundancy programming to carry failed memory addresses) based on an external address; and address storage and comparison units, each one of the address storage and comparison units being selected for programming using the second internal address.

Accordingly, the redundancy circuit with ferroelectric storage cells and a repair method allows the performance of a second repair when a defective cell is detected after a first repair or after a packaging process.

    摘要: A reference voltage supply apparatus and a driving method thereof in a ferroelectric memory device provide a reference voltage stabilized against the imprint effect thus maintaining reading reliability of the device. In the reference voltage supply apparatus (e.g., using a non-switching capacitance of a ferroelectric capacitor), a reference cell is constructed of a ferroelectric capacitor and an access switch, and provides a reference voltage to read data from a memory cell. In an active mode, the reference cell stores data of a first logic state (e.g., corresponding to the non-switching capacitance of the ferroelectric capacitor), in the reference cell, and then supplies, as a reference voltage, the voltage corresponding to the data of the first logic state to a bit line; and in a stand-by mode, a reference voltage controller stores (writes) data of a second logic state (opposite to the first logic state), into the reference cell.
