Self-reparable digital device for multiple faults based on biological attractor concepts

摘要

Provided is a fault self-repairing circuit sequentially converting an N-bit output value according to a pre-determined schedule and outputting the converted result. The fault self-repairing circuit includes different N logic modules configured to output each bit of the N bits. Here, each of the logic modules includes an internal logic. When the N-bit output value is identical to a pre-determined value, an output value of each of the logic modules is provided by the internal logic, and, when the N-bit output value is not identical to the pre-determined value, the output value of each of the logic modules is provided with a correct value provided outside each of the logic modules.
