Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0043] The present disclosure provides a non-volatile storage method and device, which realize information storage by controlling and reading the breakage degree of the conductive path of the volatile resistance transition device, thereby directly using the volatile resistance transition device for non-volatile storage .

[0044] The volatile resistance switching device of the present disclosure is used for non-volatile storage, and it no longer acts as a selector, so it no longer needs a high driving current, which is beneficial to realize low power consumption storage applications. Moreover, compared with the traditional resistance transition memory device 1S1R solution, the present disclosure uses a volatile resist...

Abstract

The present disclosure proposes a non-volatile storage method and device; wherein, the non-volatile storage method includes: using a volatile resistance transition device as a non-volatile storage storage unit; and controlling and reading the stored The degree of breakage of the conductive path of the volatile resistance switching device, thereby realizing non-volatile storage. The present disclosure adopts the volatile resistance transition device as the storage unit, which can increase the storage density of the resistance transition memory array, reduce processing steps, and reduce production cost.

Description

technical field [0001] The present disclosure relates to the technical field of memory in the microelectronics industry, and in particular to a non-volatile memory method and device. Background technique [0002] With the continuous innovation of microelectronics and semiconductor technology, FLASH storage technology is facing a series of bottleneck problems, such as the impossibility of unlimited thinning of the floating gate with the development of technology, limited data retention time, and excessive operating voltage. Among many new types of memory, resistive memory has gradually become the research focus of new non-volatile memory due to its advantages such as low operating power consumption, good endurance (Endurance), simple structure, and small device area. [0003] According to the stability of the conductive path in the case of power failure, the resistance transition device is divided into two types, a volatile resistance transition device and a non-volatile resi...
