Abstract
A memory cell power supply circuit for each column includes a first PMOS transistor and a second PMOS transistor connected together in series between a first power supply and a second power supply. A connection point between the first and second PMOS transistors is output as a memory cell power supply. A control signal which is based on a column select signal and a write control signal is input to a gate terminal of the first PMOS transistor. A signal which is an inverted version of the signal input to the gate terminal of the first PMOS transistor is input to a gate terminal of the second PMOS transistor.
