In a method of reading data from a nonvolatile memory device, a first sensing operation is performed based on a first read command. While pending reception of a second read command after the first read command, voltages of a plurality of wordlines are controlled such that a voltage of a selected wordline and voltages of unselected wordlines among the plurality of wordlines have a same voltage level. A recovery operation is omitted when the second read command is received within a reference time interval. A second sensing operation is performed based on the reception of the second read command.
