ABSTRACT:
A boosting circuit configuration with high boosting efficiency is provided which is based on a boosting circuit that performs an operation in accordance with a two-phase clock and which includes a plurality (M≧4) of boosting cell sequences (units). A boosting cell in a K-th sequence (1≦K≦M) is controlled, depending on the potential of the output terminal of a boosting cell in a KA-th sequence (KA=(K−1) when (K−1)>0, and KA=M when (K−1)=0). Thereby, before a clock input to the boosting cell in the K-th sequence goes from “L” to “H”, so that boosting is performed, a charge transfer transistor can be caused to go from the conductive state to the non-conductive state, so that a backflow of charges via charge transfer transistor can be prevented.
