Abstract
Provided herein may be a memory device and a method of operating the same. The memory device may include a memory block including a plurality of memory cells that are coupled to a plurality of word lines, a peripheral circuit configured to perform a read operation by applying a read voltage to a selected word line, among the plurality of word lines, and applying a first pass voltage to target word lines, wherein the target word lines are adjacent to the selected word line, among unselected word lines other than the selected word line, and a control logic configured to decrease the read voltage based on a read voltage variation and to decrease the first pass voltage based on a pass voltage variation when the read voltage decreases, wherein the pass voltage variation is less than the read voltage variation.
