Memristor-based multivalued logic device and operating method thereof

Abstract

The invention discloses a memristor-based nonvolatile multivalued logic device and an operating method thereof. The method provides an operating method for negation and dextrorotation of three-valued logic and multivalued T gate logic, which realizes an exhaustive set of multivalued logic, such as three-valued logic based on the multi-resistance state transition characteristic of a memristor. All the logic operation results are stored in the device in a nonvolatile resistance state, such that a logic operation function and a data storage function are realized simultaneously in the device, i.e., storage and calculation are fused; therefore, a device basis is laid for going beyond the limitation from an information device Moore's law and breaking through the Von Neumann bottleneck in a computer architecture. The memristor-based multivalued logic device disclosed by the invention can be applied to a novel solid-state memory, a logic-arithmetic unit, a programmable gate array, an on-chip system and other fields as a basic unit, and provides a new path for boosting novel computer architecture.

Description

technical field [0001] The invention belongs to the field of microelectronic devices, and more specifically relates to a multi-value logic device based on the multi-resistance state transition characteristic of a memristor and a logic operation method thereof. Background technique [0002] In the history of computer development, people have always required computers to be faster and more powerful. At present, electronic computers have shown that it is difficult to meet the new needs of human beings to deal with complex system problems. As a result, people began to seek various new types of computers, such as optical computers, molecular computers, and quantum computers. In the research of new computer architecture, the architecture based on multi-valued logic is a very promising research idea. However, due to the complex structure of existing multi-valued logic circuits and poor compatibility with existing binary systems, the development of multi-valued logic computer syst...
