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