Classification: G11C

Abstract:
A semiconductor integrated circuit device comprising:a boosted potential generating circuit for generating a boosted potential having a substantially constant level which is higher than the level of a potential supplied thereto, said boosted potential generating circuit having a variable current supply capability while the boosted potential is output;a first circuit for delivering a switching signal in accordance with a product specification;a second circuit supplied, as a power supply, with the boosted potential output by said boosted potential generating circuit, said second circuit having a load which is varied in response to the switching signal output by said first circuit;a third circuit, which receives the boosted potential output by said boosted potential generating circuit, for generating a control signal for controlling the level of the boosted potential to be substantially constant; anda fourth circuit, responsive to the switching signal and the control signal generated by said third circuit, for controlling said boosted potential generating circuit,wherein said fourth circuit increases the current supply capability of said boosted potential generating circuit in accordance with an increase in the load of said second circuit set by the switching signal and decreases the current supply capability of said boosted potential generating circuit in accordance with a decrease in the load of said second circuit set by the switching signal.
