A multi-driving apparatus by a multi-level detection which pluralizes a voltage detection level in order to effectively operate voltage generators in the voltage generation circuit, minimizes a level fluctuation, reduces noise influenced on a total operation of the apparatus, increases a reliability of the apparatus, and reduces the power-comsumption. The multi-driving apparatus includes: a level detection circuit block which receives a step-up voltage VPP or a back-bias voltage VBB as an input, and detects different level potentials; a control circuit block for controlling an operation of each generator according to a detected potential by the level detection circuit block; an oscillation circuit block which is oscillated by an enable signal being output from the control circuit block, and generates electric vibrations; and a generation circuit block which receives a control signal from the control circuit block as an input, and is comprised of plurality of generators being driven by an oscillation output from the oscillation circuit block.
