摘要：
A memory is provided with standard rows and columns and spare rows and columns for substitution for standard rows and columns found to have defective cells. Each of the decoders associated with a standard row and/or column includes provision for being disconnected if found to be associated with a defective row or column. Each of the decoders associated with a spare row and/or column is designed normally to be deselected for any address but to be able to assume the address of any disconnected row or column. Disconnection of the standard decoders and substitution of the spare decoders are made possible by appropriate inclusion of fusible links which can be selectively opened by laser irradiation.
