Abstract
In a semiconductor memory device, a decoder circuit is located between first and second memory cell arrays. A sequence of driver circuits in the decoder circuit is provided as driver circuits common to the first and second memory cell arrays. The output terminal of the driver circuit is connected directly with a data input/output portion for the first memory cell array and connected with another data input/output portion for the second memory cell array through wirings traversing the decoder circuit.
