A semiconductor device comprises a plurality of memory chips; and a controller configured to supply the plurality of memory chips with signals for controlling the plurality of memory chips. The plurality of memory chips include a chip selection signal input section configured to make a drive-targeted memory chip selected or non-selected, based on an input signal. They also include an address signal input section configured to provide a signal to address the memory chip, based on an input signal. They further include a select address signal input section configured to make the plurality of memory chips selected or non-selected, based on an input signal, and configured divertible to the address signal input section.
