ABSTRACT:
Diodes are connected between a clamp control line and respective one of data lines. A voltage of the clamp control line in a read operation is set to a value higher, by a forward voltage of the diodes or less, than a lower value among the voltages of the data line to which a selected digit line is connected. The voltages of the data lines to which only non-selected digit lines are connected are clamped to a predetermined value.
