Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. An operating method of a nonvolatile memory device, the operating method comprising:
repeatedly performing, until programming for a selected word line is completed, program loops each including a program operation and a verification operation, the program operation including a setup operation on the plurality of bit lines and an application operation of applying a program pulse to the selected word line and the verification operation including applying a verification voltage to the selected word line,
wherein the repeatedly performing includes performing a first program loop of the program loops by:
applying a first program pulse to the selected word line in a first section of the application operation,
applying a second program pulse to the selected word line in a second section of the application operation,
setting a first bit line group to a first voltage level and a second bit line group to a second voltage level lower than the first voltage level from a start of the setup operation until an end of the first section of the application operation, and
resetting the first bit line group and the second bit line group to the second voltage level in the second section of the application operation.
