Abstract
A yield recovery scheme for configuration memory of an IC device includes asserting an override configuration value on a bitline of memory cells of the configuration memory, where a data node of a faulty one of the memory cells is coupled to a node of configurable circuitry of the IC device, and asserting a wordline of the faulty memory cell while the override configuration value is asserted on the bitline to couple the bitline to the node of the configurable circuitry through the faulty memory cell (i.e., to force a state of the data node to the override configuration value). An identifier of the faulty memory cell may be stored on the IC device (e.g., E-fuses), and control circuitry of the IC device may retrieve the identifier to configure override circuitry of the IC device.
