Embodiment Construction

[0038] The technical solutions of the present invention will be further described below in conjunction with specific embodiments, and an intelligent data storage system based on piezoelectric sensors / memristors will be described in detail below in conjunction with the accompanying drawings.

[0039] as attached figure 1 As shown in the basic circuit diagram of the piezoelectric sensor, an additional external circuit is designed through components such as resistors, inductors and transistors. In the process of testing the pressure generator, it was found that the electrical signal converted from the mechanical signal cannot produce any effect under the condition of direct external load. The study found that due to the large leakage current of the pressure generator, it appears that there is only voltage to the outside. If you need to access the load, you must have enough current, so design an external circuit to reduce its leakage current.

[0040] as attached figure 1 The s...

Abstract

The invention discloses an intelligent data storage system based on a piezoelectric sensor-a memristor, which integrates the piezoelectric sensor and the memristor to convert a pressure signal into anelectrical signal so as to drive the memristor to record and store data. A protection circuit is designed at the output port of the pressure power generation sheet, so that the memristor is not broken down by an external mechanical signal. When the intelligent data storage system works, no external voltage needs to be added no matter recording, conversion or erasing. The piezoelectric sensor andthe memristor are creatively integrated into an intelligent data storage system, the piezoelectric sensor and the memristor are combined, preliminary application is formed, and through multiple tests,the system is high in stability, capable of adapting to various environments and wide in application prospect.

Description

technical field [0001] The invention relates to the field of application of nanometer materials and the field of microelectronic technology, in particular to an intelligent data storage system based on a piezoelectric sensor / memristor. Background technique [0002] As a technological science that has developed rapidly in recent years, artificial intelligence is changing human life at an unprecedented speed. Compared with humans, artificial intelligence devices have better computing speed, storage space, reliability and durability, and artificial intelligence has gradually entered all aspects of human life. [0003] Today's society is a rapidly developing society, and people's demand for data storage is growing rapidly. Processing a large amount of information puts forward higher requirements on the performance of existing storage devices. The current mainstream non-volatile storage technologies on the market are gradually encountering development bottlenecks in terms of si...
