  • Patent number: 10770142
    Abstract: The present disclosure provides a control circuit of a memory array. The control circuit includes a first switch and a set termination circuit. The first switch is connected between a first voltage source and a data line of a resistive memory cell of the memory array. The set termination circuit has a first terminal connected to a control terminal of the first switch and a second terminal connected to the data line of the resistive memory cell of the memory array. When a data line voltage of the data line decreases to be lower than a first voltage in a first duration of the resistive memory cell performing a set operation, the set termination circuit turns off the first switch to terminate the set operation by stopping providing the first voltage of the first voltage source to the data line.
