ABSTRACT:
An integrated circuit and a method for configuring programmable logic thereof are described. A data register and an address register are coupled to an array of memory cells of the integrated circuit. Address storage is configurable for storing an address associated configuration data targeted for being written to at least one defective memory cell of the array of memory cells. Data storage is configured to store the configuration data associated with the at least one defective memory cell. A controller is configured to cause the address to be loaded into the address register and the configuration data to be loaded into the data register. The controller is configured to maintain a write state for continually writing the configuration data to the array of memory cells responsive to the address during operation of the integrated circuit.
