  • Column replacement with non-dedicated replacement columns
    Patent number: 10908838
    Abstract: Apparatuses, systems, and methods are presented for column replacement. An input register, which includes a set of input divisions, may receive write data for a memory array. An output register, which includes a set of normal output divisions and a set of replacement output divisions, may output write data to an array. A column replacement circuit may selectively couple input divisions to output divisions. A column replacement circuit may couple normal output divisions for functional columns of an array to corresponding input divisions. A column replacement circuit may couple replacement output divisions for functional columns of an array to input divisions selected by the column replacement circuit, which may be corresponding input divisions or other input divisions.
