Abstract
A self-repair memory circuit includes a cell array, a controller, a row repair decoder, and a column repair decoder. The cell array includes rows and columns of memory cells. The controller receives an input indicating row repair or column repair, and a repair address shared by the row repair and the column repair of the cell array. The row repair decoder maps the repair address of a defective row to a redundant row of the cell array when the input indicates the row repair. The column repair decoder maps the repair address of a defective column to another column of the cell array when the input indicates the column repair.
