Solution Overview

Problem

Existing power management technologies for integrated circuits rely on external protection circuits and lack internal self-repair mechanisms, making them vulnerable to power supply fluctuations that can cause damage or malfunction.

Innovation Solution

An integrated circuit self-repair method where a main register sets and transmits a predetermined logic state to multiple registers, allowing the circuit to correct any deviations caused by power emergencies by outputting the correct logic state to affected registers, ensuring continuous operation and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external protection circuits are used to protect the integrated circuit from power supply fluctuations, then the integrated circuit can be protected from damage, but the system complexity increases and the protection cannot be provided from inside the integrated circuit

Engineering Contradiction:
Improveprotection from power supply fluctuationsVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the protection circuit functionality directly into the integrated circuit chip, merging previously separate external protection circuits with the main circuit. This integration reduces system complexity by eliminating external components while maintaining the protection function against power supply fluctuations through the self-repair mechanism using multiple registers and logic state correction.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If external protection circuits are designed outside the integrated circuit, then the protection function is provided, but the protection cannot be provided from inside the integrated circuit and response time is delayed

Engineering Contradiction:
Improveprotection functionVSAvoidresponse time
Core Design Contradiction:
ReliabilityVSSpeed

Solution Approach 1:

The patent implements preliminary action by pre-configuring multiple registers (first register, second register, third register) with predetermined logic states before power supply fluctuations occur. When a fluctuation happens, the circuit can immediately detect and correct the logic state without waiting for external protection circuits, achieving faster response time through pre-prepared correction mechanisms.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If multiple registers are used for self-repair, then the integrated circuit can correct logic state deviations caused by power emergencies, but the device complexity increases

Engineering Contradiction:
Improveself-repair capabilityVSAvoidcircuit complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by implementing self-repair capability specifically in the register logic section where power supply fluctuations cause the most critical damage. Instead of making the entire system complex, only the essential register elements (first, second, third registers) are equipped with self-repair functionality through predetermined logic states, keeping the rest of the system simple while achieving reliable protection where needed most.

Inventive Principle:
Principle #3Local quality

AI summary

An integrated circuit self-repair method and an integrated circuit thereof are provided. The integrated circuit self-repair method includes: transmitting, by a main register, a predetermined logic state to at least three registers, and setting the at least three registers to the predetermined logic state; outputting, according to the predetermined logic state in the at least three registers, the predetermined logic state to drive a controlled circuit to perform a function; and when a minority of the at least three registers are changed to an opposite logic state due to an emergency occurring at an input power source, outputting the predetermined logic state according to the predetermined logic state of the remaining registers, and transmitting the predetermined logic state back to the register that is in the opposite logic state, to correct the opposite logic state to the predetermined logic state.
