Abstract
A non-volatile memory apparatus includes a memory cell coupled between a global bit line and a global word line. A bit line control circuit configured to apply a bit line read bias voltage to the global bit line based on a read signal. A snap-back detection circuit coupled to the global word line, and configured to generate a data output signal and a current enable signal by detecting a snap-back of the memory cell. A word line control circuit configured to apply a word line read bias voltage to the global word line based on the read signal, and may increase an amount of a current flowing through the memory cell based on the current enable signal.
