Claim 1:
2. The method of claim 1, wherein performing the plurality of sensing operations using the plurality of read voltages on the selected page comprises:
storing data stored in the memory cells included in the selected page in a data latch of a corresponding page buffer, respectively;
performing a threshold voltage sensing operation of the memory cells included in the selected page using a selected read voltage among the plurality of read voltages, and storing bit data generated as a result of sensing in a sensing latch included in each of a plurality of page buffers;
transmitting the bit data stored in the sensing latch to a corresponding sense out node; and
removing a sensing result corresponding to remaining states except for the target state by applying a control signal corresponding to the target state to the plurality of page buffers.
