Semiconductor device having single-ended sensing amplifier

Image Number 12 for United States Patent #7990793.

A semiconductor device has a DRAM cell configured from an information charge accumulating capacitor and a memory cell selecting transistor, the threshold voltage value of a MOS transistor that constitutes a sense circuit is monitored, and the monitored threshold voltage value of the MOS transistor is converted through the use of a transfer ratio that is determined based on the capacitance of the information charge accumulating capacitor and the parasitic capacitance of the bit line. The converted voltage value is level-shifted so that the pre-charge voltage of a pre-charge circuit is a pre-set voltage, a current feeding capability is added to the level-shifted voltage value, and the voltage is fed as the pre-charge voltage.
