ABSTRACT:
When the output of a boosted voltage is started by a boosted voltage generation circuit, the voltage supplied to memory cells and level shift circuits side through a current mirror circuit is detected by a voltage divider circuit. Comparators compare the detected voltage with a reference voltage. Based on the result of comparison, FETs are brought into conduction as required. The rate of voltage rise provided by the current mirror circuit is thus controlled.
