An apparatus, system, and method are disclosed for a storage device’s enforcing write recovery of erroneous data. Specifically this invention relates to mutants of Neisseria containing mutations in a major outer membrane protein gene such that no immunologically functional polypeptides encoded by said gene are produced. A first resistor is connected across the emitters of the bipolar transistors. Match circuitry substitutes at least one redundant memory cell from the first redundant cell array for the at least one defective memory cell in the first memory cell array when a first memory access corresponds to the first cached address.
