Patent abstract
In order to successively perform refresh operations, a semiconductor device has a plurality of regions performing a repair independently from each other, even when the repair is carried out in the region by a replacement with a repair memory block included in a plate included in each region. Specifically, the successive refresh operations are performed by alternately activating word lines in the respective regions so as to ensure a sufficiently long precharge period.
