Abstract

PURPOSE:To make a data read time high-speed by connecting a switching element, where data opposite to column line data is inputted, in parallel to the load element, which sets the level of the column line, in the semiconductor memory. CONSTITUTION:Data detector circuit 8 outputs data opposite to column line data to turn on and off element 10 only during CS signal input, however, element 10 is floating during other periods. When column line 3o in ''1'' state is selected and a CS signal is inputted, element 10 is turned off. Next, when the row line is selected and element 4o is turned on, the state of column line 3o becomes ''0'' because charge is discharged. This discharge time is short because element 10 is turned off and only element 7 disturbs this discharge. Reversely, when the column line is ''0'', the column line charge time becomes short because element 10 is turned on.
