Abstract
A boosting circuit included in a semiconductor integrated circuit for efficiently stabilizing a boosted potential, including a plurality of boosting circuits and a timing control circuit for distributing the operations of the boosting circuits. Boosting operations per operating cycle of a memory increase in number so as to suppress a reduction in boosted source potential, the reduction being caused by consumption. Moreover, it is possible to perform a boosting operation in a time period equal to that of consuming boosted source potential, resulting in an efficient boosting operation.
