Abstract

Integrated circuits (10) with repairable logic regions are provided. Each logic region may be organized into a predetermined number of rows of logic circuitry, one of which serves as a spare row (106'). A repairable region (100) may be operable in normal mode or redundant mode. In normal mode, the spare row (106') is deactivated. When one of the logic region rows (106) contains defective circuitry, that logic region (106) is operated in redundant mode so that each row below the bad row is shifted down by one row and the spare row (106') is engaged to serve as the last row to repair that region. Each row (106) may include a multiplexer and an associated driver that drives a corresponding vertical routing segment from one row to the next. Each vertical routing segment has the option of being driven by its logically equivalent vertical wire in the immediate preceding row by configuring the corresponding multiplexer.
