Claim 14:
15. A method for self-repair of a memory circuit, comprising:
receiving, by a controller of the memory circuit, an input of a fuse signal that indicates a repair address shared by row repair and column repair of a cell array, the fuse signal including an enable signal that indicates whether the repair address is for theindicating row repair or the column repair, wherein the cell array that-includes a plurality of rows and a plurality of columns of memory cells;
mapping, by a row repair decoder of the memory circuit, the repair address of a defective row to a redundant row of the cell array, wherein the repair address is received by the row repair decoder from the controller when the enable signal indicates the row repair; and
mapping, by a column repair decoder of the memory circuit, the repair address of a defective column to another column, wherein the repair address is received by the column repair decoder from the controller when the enable signal indicates the column repair,
wherein the memory circuit is part of a chip and is to receive the fuse signal from a fuse memory through a plurality of fuse pins of the chip.
