Abstract:
1. A method of programming a nonvolatile memory device, the method comprising: a bit line voltage set-up step of receiving a program command and data to be programmed and setting up a voltage of a selected bit line according to a state of program data; a program step of supplying a program voltage to a word line selected for a program in response to a control signal for setting up the program voltage, supplying a first pass voltage to unselected word lines, and then performing the program; and a program verification step of, in a state in which the first pass voltage supplied to the unselected word lines has shifted to a second pass voltage in response to a control signal subsequent to the control signal for setting up the program voltage and is used to set a verification voltage, performing a program verification operation by supplying the verification voltage to the selected word line.
