ABSTRACT:
A plurality of p-MOSFETs connected to a power supply line is turned on to precharge bit lines. A precharge cancel signal generated by a NOR circuit and an inverter performs precharge control to turn off the p-MOSFETs to set the bit lines in a floating state during the period of a standby mode, or turn on the p-MOSFETs to precharge the bit lines during the period of a read mode or write mode.
