ABSTRACT:
Provided is a semiconductor integrated circuit capable of reducing power consumption in an electric potential converting circuit for converting an electric potential of a bit line. The semiconductor integrated circuit according to the present invention comprises bit lines BL1 and BL2, a precharge circuit PCC which is connected to the bit lines BL1 and BL2, an electric potential converting circuit SA, and a memory cell MC. The electric potential converting circuit SA has a current path for transistors T3, T4 and T6 and a current path for the transistor T3 and transistors T5 and T9 provided between a high potential V2 and a ground potential GND. Respective gate electrodes of the transistors T3, T4, T6 and T9 receive a mode signal PC, and respective gate electrodes of the transistors T4 and T5 are connected to the bit lines BL1 and BL2.
