Abstract
Provided are a non-volatile memory device, a storage device including the same, and a method of performing a programming operation on the same. The method includes performing a program operation including applying a desired first program voltage to a selected word line of the memory device, the selected word line including a plurality of memory cells, performing a verification operation including sensing a first sensing value corresponding to an output of the selected word line based on a first verify voltage, and counting a number of on-cells of the selected word line based on the first sensing value to determine a first count value, determining whether a first program state of the selected word line has been verified based on the first count value and at least one reference value, and setting a second program voltage based on results of the determining whether the first program state has been verified.
