Abstract
An integrated circuit device includes a data driver block, a memory block, an information storage block in which an address of a defective cell of the memory block is programmed and stored as a defective address, and a switch control circuit which performs control for switching access to the defective cell to access to a redundant cell. A row address of the defective cell having the row address and a column address is stored in the information storage block as the defective address. The switch control circuit performs control for switching access to the defective cell to access to the redundant cell by comparing a row address for display panel access with the defective address during the display panel access and comparing a row address for host access using the row address and a column address with the defective address during the host access.
