Description

technical field [0001] The invention relates to the field of semiconductor devices, in particular to a random magnetic tunnel junction device with controllable flipping probability and an application method of the random magnetic tunnel junction device with controllable flipping probability. Background technique [0002] With the increasing enhancement of integrated electrode technology and adapting to the increasing computing needs, the scale and complexity of integrated circuits are getting higher and higher. However, with the continuous development of artificial intelligence, big data, and the Internet of Things, problems that need to be solved The problem is also getting more complex. Due to the limitation of the processing capacity of the integrated circuit itself, the development of the integrated circuit is becoming more and more out of touch. Especially in the fields of sampling, reasoning, optimization, and reversible computing, because traditional Turing electroni...
