This rule is known by another precise word in its true meaning. We can get it as a scoring rule, a Dennard scoring rule or even a Dennard Scaling specification, but they all point to the same goal.
Dennard's law: a sequence in Moore's Law for the Use of Power
If Moore's law imposes an increase in the number of transistors, it does not refer to the operation it represents. Here it goes completely into Dennard's Law, which was created Robert H. Dennard, an engineer born in 1932 in the USA and among other things invented DRAM as we know it today.
In 1974, he enacted his surname on the basis that MOSFETs would continue to operate in the future as a switch and that they would be electrically controlled, but instead decided that as the metal size diminished, it made use of its power for transistors itself.
And here it makes sense to meet Moore & # 39; s famous law, because as it happens in this case, the reduction of transistors and their increase is not linear and even though using less power to the same millions and cheaper, the physical limit would violate the stated rule.
Power leak, a gap in the law of use
As we have seen in other articles focusing on lithographic processes for 7nm and 5nm, it is not easy to reduce the number of nanometers in formation and death. Each reduction of the transistors introduces a series of imaginary leakages depending on the sequence of vibrational energy the circuit contains.
This means that switching to a smaller transistor with a lower threshold requires more control of the transistor, smaller gate and lower dielectric size. The problem is that manufacturers are able to improve all without electricity, which is an ongoing problem in the industry.
For this reason, some engineers argue that the law does not apply now, although some continue to defend it for obvious reasons. In any case, both Moore's Law and Dennard's Law are tightly linked to another law rather than a form of overcoming the industry, known as Koomey's Law.
This rule also looks at specific uses, but we will see in the next article to explain it in more detail and understand how the debate remains in this very broad field.
