Abstract
A semiconductor memory apparatus includes a driving voltage providing circuit suitable for selectively providing a first driving voltage, a second driving voltage, a third driving voltage, a ground voltage, and a precharge voltage to a first driving line and a second driving line in response to an active signal, a cell characteristic information signal, and a precharge signal. The semiconductor memory apparatus also includes a sense amplifier suitable for operating by being applied with voltages provided from the first and second driving lines.
