Abstract
In order to eliminate erroneous reading of data by preventing noise which might otherwise be transmitted at the data read time through parasitic capacitance in the data lines to other data lines, switches (Qt,and Qt,′) are interposed between a sense amplifier (SA) for amplifying the potential of a data line (DL) and the data line, and the sense amplifier is fed with an operating voltage after the potential of the data line is transmitted to the sense amplifier, and the switch is turned off.
