Abstract
A voltage generation circuit comprises a voltage generation control unit configured to output one of a first voltage level determination signal having a fixed data value and a second voltage level determination signal having a varying data value in response to a selection signal, and a voltage generation unit configured to generate a voltage having a single pulse form or a voltage having a pulse form whose rising edge portion rises in incremental voltage steps in response to the voltage level determination signal outputted from the voltage generation control unit.
