Abstract
A nonvolatile memory apparatus includes a memory cell configured to receive a first current and a second current through a bit line which is connected to a sensing node; a sensing node level control unit configured to be driven in response to a control signal, compare a reference voltage and a voltage of the sensing node, and output a driving signal to a driving node; a first current driving unit configured to output the first current to the driving node by using a first driving voltage in response to the driving signal; and a current control unit configured to perform a discharge operation of the bit line or electrically connect the driving node and the sensing node, in response to the control signal.
