  • Patent number: 9275743
    Abstract: An operating method of a semiconductor device is provided. The operating method of the semiconductor memory device includes programming a second source select transistor electrically coupled to a common source line through a first source select transistor; reprogramming the second source select transistor when a threshold voltage of the second source select transistor is less than a target voltage, and ending a program for the second source select transistor when the threshold voltage of the second source select transistor is greater than or equal to the target voltage. The programming includes electrically decoupling the second source select transistor from the common source line by turning off the first source select transistor.
