Abstract
A semiconductor integrated circuit includes memory cell blocks having memory cells arranged in matrix, sense amplifiers, each located adjacent to the memory cells, and sense amplifier control circuits, each of the sense amplifier control circuit being located on outside of the memory cell block. The sense amplifier control circuit has a standard voltage generating circuit and a control circuit for receiving the standard voltage and for transferring a driver signal to the sense amplifier to control the charging ability of the sense amplifier. The source voltage has three voltage regions, first, intermediate, and second regions. In the first voltage region, the potential of the driver signal increases with the increase of the source voltage. In the intermediate voltage region (2.7 to 3 Volt), the potential of the driver signal is changed oppose to the change of the source voltage, and in the second voltage region, the potential of the driver signal decreases with the increase of the source voltage.
