Abstract:
1. A system comprising: a memory array circuit comprising redundant memory cells for replacing defective memory cells detected after fabrication; a non memory array circuit, the non memory array circuit comprising circuitry for adjustment after fabrication of an operating parameter of a group consisting of an operating current, an operating voltage, a resistance, a capacitance, a conductance, an inductance, a frequency, a timing characteristic, a tuning characteristic, selection of one circuit from a set of circuits, and an operating mode; a one time programmable element, the one time programmable element programmable for storing information for modifying the system after fabrication, the one time programmable element is programmably assignable after fabrication to any one of a group of circuits comprising the memory array circuit and the non memory array circuit, wherein the one time programmable element is programmable to store information for any one of the group comprising replacing a defective memory cell of the memory array circuit detected after fabrication and adjusting after fabrication of the operating parameter of the non memory array circuit; control circuitry coupled to the one time programmable element to receive programmed information stored in the one time programmable element, the control circuitry is coupled to the memory array circuit and to the non memory array circuit to provide the programmed information stored in the one time programmable element to the one of the group of circuits that the one time programmable element is programmably assigned to.
