  • DRAM positive wordline voltage compensation device for array device threshold voltage and voltage compensating method thereof
    Patent number: 7940549
    Abstract: The configurations of a DRAM positive wordline voltage compensation device and a voltage compensating method thereof are provided in the present invention. The proposed device includes a comparator having a first input terminal receiving a positive wordline voltage feedback signal, a second input terminal receiving a compensating reference of array device threshold voltage and an output terminal generating a first enable signal, an oscillator receiving the first enable signal and generating an oscillating signal when the first enable signal is active and a charge pump having a first input terminal receiving a second enable signal, a second input terminal receiving the oscillating signal and an output terminal generating a positive wordline voltage being a sum of a bitline high voltage, an array device threshold voltage and a voltage margin.
