Abstract
A semiconductor memory apparatus includes a bias voltage generation circuit configured to generate a bias voltage according to a read voltage or a write voltage in response to a read signal and a write signal, a data discrimination circuit configured to generate a set enable signal and a reset enable signal in response to data and the write signal. The semiconductor memory apparatus also includes a current selection circuit configured to generate a first current in response to the read signal, the set enable signal, and the reset enable signal. The semiconductor memory apparatus further includes a driver configured to receive the first current and generate a second current in response to a voltage level of the bias voltage, and a first switch configured to provide the second current to a memory cell in response to the read signal and the write signal.
