Abstract
When a stage increasing signal, which is input into a sub boosting circuit, is at the L level, three boosting stages are used within the sub boosting circuit to boost a supply potential. On the other hand, when the stage increasing signal is at an H level, four boosting stages are used within the sub boosting circuit to boost the supply potential. Thus, by the semiconductor integrated circuit device of the invention, an internal potential can be boosted at a high speed while power consumption can be reduced.
