Abstract
A non-volatile memory device includes a memory cell including a resistance variable device and a switching unit for controlling a current flowing through the resistance variable device; a read reference voltage generator configured to generate a reference voltage according to a skew occurring in the switching unit; and a sense amplifier configured to sense a voltage corresponding to the current that flows through the resistance variable device based on the reference voltage.
