ABSTRACT:
A voltage of a bit line connected to a memory cell is stepped up up to a power supply voltage by a precharge circuit. Before data is read from the memory cell, the voltage of the bit line is stepped down to a voltage level lower than the power supply voltage by a step-down circuit. A precharge switching element controls a connection between a high-potential-side power supply and the precharge circuit and a connection between a low-potential-side power supply and the precharge circuit. A power supply connecting circuit is provided between the precharge switching element and the high-potential-side power supply. A ground connecting circuit is provided between a connecting point at which the precharge switching element is connected to the power supply connecting circuit and the low-potential-side power supply.
