Abstract
An integrated circuitis formed of multiple layers of circuitssuperimposed to produce stacks of circuit blocks. Stack control circuitryis associated with the input and output signals from the circuit blocks to direct these to/from the currently active circuit block(s) as appropriate. The superimposed circuit blocksprovide redundancy for each other, both for manufacturing defect resistance and for operational redundancy, such as providing multiple modular redundancy in safety critical environments.
