Electric field write-in and resistance readout solid-state storage component, storer and read-write method of storer

Abstract

The invention provides an electric field write-in and resistance readout solid-state storer component, a storer and a read-write method of the storer. The invention relates to a novel nonvolatile solid-state storage component, a storer, and a corresponding write-in and readout method. The solid-state storage component comprises a bottom electrode layer, a ferroelectricity piezoelectric layer formed on the bottom electrode layer, a resistive layer which is close to the ferroelectricity piezoelectric layer and placed on the ferroelectricity piezoelectric layer, and a top electrode layer which is placed on the resistive layer, wherein the ferroelectricity piezoelectric layer is used as an information storage layer and has two or more straining states under the effect of the electric field, and the resistive layer has two or more nonvolatile resistance states, so that the resistive layer can be used as the information readout layer. According to the solid-state storage component, the information is written in through the electric field and can be read out in a non-destructive manner; and the solid-stage storage component has the advantages of being low in power consumption, nonvolatile, fast in storage speed, and high in storage density.

Description

technical field [0001] The invention belongs to the technical field of information storage, and in particular relates to nonvolatile solid-state storage components and memories, in particular to nonvolatile solid-state storage components, storage components, and storage and information writing and reading of nonvolatile electric field writing and resistance reading method. Background technique [0002] Information storage technology is an important link in the development of modern electronics industry. At the same time, realizing high density, low power consumption, non-volatile and high-speed storage is the goal that people dream of. To this end, people have developed a variety of storage devices, mainly including: optical storage media that use light to read and write, such as CDs and DVDs; magnetic media storage devices that use magnetic fields to read and write, such as hard disks; Storage devices, such as magnetoresistive random access memory devices (MRAM); electric...

AI Technical Summary

Problems solved by technology

However, due to the disadvantages of high cost, high write power consumption, and slow write speed, SSDs still use hard disks for data storage in large-capacity storage.

[0004] The above storage technologies either use a strong magnetic field generated by current to write information (typical representative: hard disk), or use voltage to regulate the charge of the storage unit to write and read information (typical representative: solid-state memory), so these storage technologies When writing information, the power consumption is very large, and the writing is slow. These shortcomings limit their overall storage performance
