1. A program and verify method of a nonvolatile memory device, comprising:
- precharging an output terminal of a block selector to a second level by applying first and second control signals of a first level, which is higher than the second level, to a block switch;
making the output terminal of the block selector float; and
applying a program voltage and a verify voltage sequentially through a global word line in the state where the output terminal floats.

Abstract
A program and verify method of a nonvolatile memory device, which can minimize the time taken for program and verify operations. The program and verify method includes precharging an output terminal of a block selector to a second level, making the output terminal of the block selector float, and, in the state where the output terminal floats, sequentially applying a program voltage and a verify voltage through a global word line.
