ABSTRACT:
In a booster circuit which is operated with a two-phase clock and in which a plurality of (M≧4) lines of boosting cells constitute a unit, a boosting cell in the K-th line (1≦K≦M) is controlled, depending on the voltage of the input terminal of a boosting cell in the KA-th line (KA=(K−1) when (K−1)>0, and KA=M when (K−1)=0). As a result, a charge transfer transistor can transition from the conductive state to the non-conductive state before a clock input to the boosting cell in the K-th line transitions from low to high and then boosting operation is performed. As a result, the backflow of charge via the charge transfer transistor can be reduced or prevented.
