Title (EN) MEMORY WITH REDUNDANT ROWS AND COLUMNS
(FR) MEMOIRE A RANGEES ET COLONNES REDONDANTES
Abstract: front page image
(EN)A memory is provided with standard rows and columns and spare rows (14) and columns (13) for substitution for standard rows and columns found to have defective cells. Each of the decoders (15, 16) 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 (30) 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 (20) and substitution of the spare decoders (30) are made possible by appropriate inclusion of fusible links (21, 41) which can be selectively opened by laser irradiation.
(FR)Une memoire est pourvue de rangees et de colonnes standard et des rangees (14) et des colonnes (13) de remplacement pour la substitution a des rangees et colonnes standard qui presentent des cellules deficientes. Chacun des decodeurs (15, 16) associe a une rangee standard et/ou une colonne comprend des moyens permettant de le deconnecter s"il se trouve qu"il est associe avec une rangee ou une colonne deficiente. Chacun des decodeurs (30) associe a une rangee et/ou une colonne de remplacement est destine normalement a etre non-selectionne pour toute adresse mais a etre apte a assurer l"adresse de n"importe quelle rangee ou colonne deconnectee. La deconnection des decodeurs standard de remplacement (30) est rendu possible par l"inclusion appropriee de liaisons fusibles (21, 41) qui peuvent etre selectivement ouvertes par irradiation laser.
