Abstract
A semiconductor storage device has a function of simultaneously activating a plurality of word lines connected to the same bit line via cell transistors. The semiconductor storage device comprises a column redundancy system that sets repair regions of column redundancy based on row addresses. By the column redundancy system, the repair regions are set to cause the plurality of word lines which can be activated together to belong to the same repair region, when the repair regions are set to divide the bit line.
