Encoding method and encoder based on resistance random access memory

Abstract

The invention provides an encoding method and an encoder based on a resistance random access memory. The encoding method comprises the following steps of (1) adding n types of established voltages to the resistance random access memory, carrying out set operation on the resistance random access memory, and enabling the resistance random access memory to be in n types of low resistance states, wherein the n is larger than or equal to 2, (2) adding m types of reset voltages to the resistance random access memory, carrying out reset operation on the resistance random access memory, enabling the n types of the low resistance states to respectively form m types of high resistance states, and outputting the n*m types of the high resistance states, wherein the m is larger than or equal to 2. According to the encoding method, a traditional CMOS is replaced, and the function of complex encoding is achieved. The invention further provides an encoder based on the resistance random access memory.

Description

technical field [0001] The invention relates to the technical field of semiconductor integrated circuits and its manufacture, in particular to an encoding method and an encoder based on a resistive variable memory. Background technique [0002] Traditional computers usually use binary logic to implement information processing and storage functions, and its information processing (or calculation) and storage are implemented in different devices or functional modules, and the operation process is usually a step-by-step serial process. Dozens or even hundreds of MOS transistors are often required to complete a simple arithmetic operation or encoding and decoding operations; therefore, technicians in the industry proposed to use the multi-valued phenomenon and multi-valued logic generated by metal oxides in the resistive switching process, Achieve higher efficiency and simpler structure.
