An integrated circuit comprises a volatile memory array, a non-volatile memory array, a plurality of registers, and a plurality of flip-flops. A portion of the non-volatile memory array is used for storing an address of a defective memory cell of the volatile memory array. The plurality of registers is coupled to the non-volatile memory array. The plurality of registers temporarily stores the address of the defective memory cell during a normal operating mode of the integrated circuit. Each of the plurality of flip-flops are used for substituting for a defective memory cell of the volatile memory array and are implemented on the integrated circuit physically separate from the volatile memory array.
