Abstract

To provide a magnetic storage element in which a writing current is reduced while maintaining the magnetism-retaining characteristics of a storage layer; and an electronic device. A magnetic storage element, provided with: a spin orbit layer extended in one direction; a write line electrically connected to the spin orbit layer, the write line channeling a current in the extension direction of thespin orbit layer; a tunnel junction element provided on the spin orbit layer by laminating a memory layer, an insulator layer, and a magnetization fixed layer in the stated order; and a non-magnetic layer having a film thickness of 2 nm or below, the non-magnetic layer being provided at one of the lamination positions between the spin orbit layer and the insulator layer.

Description

technical field [0001] The present disclosure relates to a magnetic memory element and an electronic device. Background technique [0002] With the continuous improvement of the performance of various information equipment, the built-in storage devices in various information equipment also show the improvement of integration, the improvement of speed and the reduction of power consumption. Accordingly, the performance of memory elements using semiconductors is also improving. [0003] For example, flash memory rather than hard drive devices are becoming more and more popular as mass file storage. In addition, various types of storage elements such as FeRAM (Ferroelectric Random Access Memory), PCRAM (Phase Change Random Access Memory) or MRAM (Magnetic Random Access Memory) instead of NOR type flash memory and DRAM (Dynamic Random Access Memory) Access memory), is being developed as code storage or working memory. [0004] For example, MRAMs, in which information is store...
