Abstract
In a semiconductor device having a redundant memory, the area of the device is reduced and a time required to transfer relief information is reduced. Moreover, a transfer control of relief information is facilitated. A first relief information storing unit stores relief information for relieving a redundant memory having a defective cell. A plurality of redundant memories share a second relief information storing unit. The second relief information storing unit is connected in series to the first relief information storing unit. The relief information is transferred from the first relief information storing unit to the second relief information storing unit.
