Benefits of technology

This new technology helps prevent damage from over-aging or leaking electronic components while still maintain their effectiveness for use with other devices that require less energy than usual.

Problems solved by technology

This patents discuss various technical methods aimed towards decreasing negative effects associated with increased resistance in semiconductor processes such as complementary metal-on-silicone (CMOS), nitride thin film deposition, ion implantations during fabricating processes, dopants migration from defects in materials, impurities generated within these layers, and stress relaxation mechanisms leading to reduced lifetimes over time. However, this issue can lead to malfunctions in electronic components like memristive elements, causing delays in processing operations. To address it, some conventional measures including double-stress thermostat activation and passivation masking were developed but they resulted in increases in leakage currents and static work functions.

Embodiment Construction

[0028] The gate replacement method proposed by the present invention to simultaneously reduce the aging of integrated circuits and reduce leakage power consumption is described as follows in conjunction with the accompanying drawings.

[0029] Although many scholars have proposed methods to alleviate the NBTI aging effect and reduce leakage power consumption, so far, no scholars have proposed an effective method that can simultaneously achieve these two purposes, and the method proposed by the present invention is in the circuit design Use a small amount of time to carry out computer simulation, calculate the optimal replacement and distribution scheme of the logic gates in the circuit, manufacture the circuit according to the calculated replacement and distribution scheme, and use the sleep signal to control the circuit when it is idle without affecting the performance of the circuit The logic values ​​of these replaced gates achieve the dual purpose of simultaneously reducing...
