Abstract
The present disclosure relates to a memory device, and a method of operating the memory device that includes a memory block including memory cells. The memory device also includes a voltage generator configured to apply a read voltage and pass voltages to word lines coupled to the memory block. The voltage generator is configured to apply the read voltage to a selected word line among the word lines and apply different pass voltages to unselected word lines symmetrical to each other with respect to the selected word line depending on distances to the selected word line, during a read operation on the memory block.
