Sensing, storage and calculation integrated micro-nano electronic device and preparation method thereof

Abstract

The invention discloses a sensing, storage and calculation integrated micro-nano electronic device and a preparation method thereof. The micro-nano electronic device comprises a gas sensing module, a signal judgment module, a signal storage and calculation module, a working array resetting module and a substrate which are sequentially laid from top to bottom, wherein the gas sensing module is used for adsorbing to-be-detected gas and determining a current change value and a voltage change value according to the concentration change of carriers participating in particle migration; the signal judgment module is used for determining the mode of a calculation unit participating in work in the signal storage and calculation module according to the voltage change value; the signal storage and calculation module is used for storing the current change value and calculating the concentration of to-be-detected gas according to the current change value; and the working array resetting module is used for performing line-by-line resetting operation when all the calculation units in the signal storage and calculation module participate in working. According to the invention, the energy consumption of the device can be reduced while storage efficiency is improved.

Description

technical field [0001] The invention relates to the field of micro-nano electronic devices, in particular to a sensor-memory-computing integrated micro-nano electronic device and a preparation method thereof. Background technique [0002] With the continuous innovation of computer and micro-processing technology, semiconductor micro-nano electronics technology has become a pillar industry for the development of modern science and technology. In recent years, with the rise of emerging technologies and industries such as the Internet of Things, edge computing, deep learning, and artificial intelligence, data and information have become indispensable resources in the era of big data. The calculation method (serial and iterative processing) of the traditional Von Neumann architecture is a centralized sequential operation based on clock cycles, and a modular framework design with separate storage and calculation units is adopted. Data needs to be stored in the sensing nodes (sens...
