ABSTRACT:
The present invention is directed to repair a defective bit included in a memory in a semiconductor integrated circuit device for a display controller. The semiconductor integrated circuit device has a display memory capable of storing display data in a storage area, and a repair circuit capable of repairing a defect by replacing an area including a defect in the display memory with a spare storage area provided on the outside of a regular storage area for storing the display data. The device further includes a selector circuit provided on a transmission path of output data from the display memory and selectively replacing output data from the regular storage area with output data from the spare storage area in accordance with a control signal from the repair circuit. By selectively replacing the output data from the regular storage area with output data from the spare storage area in accordance with a control signal from the repair circuit, a defective bit is repaired.
