    摘要: In a ferroelectric random access memory device that can allow a stable burst read operation and a method of driving a ferroelectric random access memory device thereof, the ferroelectric random access memory device comprises first and second memory cell sections, each comprising a plurality of ferroelectric memory cells, and a read circuit that sequentially performs a burst read operation on the first and second memory cell sections such that a read operation of the first memory cell section partially overlaps a read operation of the second memory cell section. When a chip is disabled during the read operation of the first memory cell section, the read circuit writes back data in the second memory cell section in response to the extent to which the read operation of the second memory cell section has been performed.

    摘要: A redundancy circuit and repair method for a semiconductor memory device. 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. The address storage and comparison units comprise ferroelectric storage cells that store the address of a defective (failed) main memory cell and outputs a redundancy decoder enable signal in response to a first internal address matching the stored (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.
