  • Nonvolatile memory device and method of programming the same
    Patent number: 8264887
    Abstract: A nonvolatile memory device includes a memory block including a number of cell strings, a channel voltage detection unit configured to detect channel voltages of the cell strings in which the channel voltages are changed based on voltages supplied to memory cells of the cell strings during a program operation and to generate channel voltage code based on an average channel voltage of the detected channel voltages, and a voltage supply unit configured to change a level of a pass voltage of the voltages supplied to memory cells in which the pass voltage is supplied to the memory cells during the program operation according to the channel voltage code.
    Type: Grant
