  • Patent number: 8068113
    Abstract: The present invention provides a display control semiconductor integrated circuit having therein a RAM, capable of repairing a defective bit included in the RAM and improving the yield without significantly increasing the occupation area. A liquid crystal controller/driver in which a RAM for storing display data is provided in a chip and the storage capacity of the built-in RAM is determined according to the size of a display screen of a liquid crystal panel to be driven, includes a fuse circuit for setting a defect address, and a comparing circuit for comparing the defect address set in the fuse circuit with an input address. The liquid crystal controller/driver also has a redundant circuit, when the addresses match each other, for replacing the input address with an address that instructs the spare memory area and supplying the address to an address decoder.
