Abstract
A method of operating a memory device includes performing a first program operation on first memory cells connected to a first channel region among a plurality of channel regions formed by separating one channel hole into the plurality of channel regions, based on a first verify voltage. The method also includes performing a second program operation on second memory cells connected to a second channel region among the plurality of channel regions, based on a second verify voltage. The method further includes determining third memory cells having a threshold voltage lower than a target threshold voltage distribution among the first memory cells while performing the second program operation. The method additionally includes performing a third program operation on the third memory cells.
