PURPOSE: A nonvolatile memory and an operating method thereof are provided to reduce a peak current by completely discharging or pre-charging a selected bit line by a page buffer unit after the selected bit lien is partially pre-charged. CONSTITUTION: An even bit line is connected to an even cell string. An odd bit line is connected to an odd cell string(320). A bit line precharge unit(330) precharges the even bit line and the odd bit line before a program operation. The bit line precharge unit precharges the bit line among the even bit line and the odd bit line below a target value and precharges the non-selected bit line to the target value.
