Title:
MAGNETIC TUNNEL JUNCTION, MANUFACTURING METHOD, SPIN DIODE, AND MEMORY
Document Type and Number:
WIPO Patent Application WO/2021/016837
Kind Code:
A8
Abstract:
Provided in the present application are a magnetic tunnel junction, a manufacturing method, a spin diode, and a memory. With respect to the problem of a low tunnel polarization current transmission rate and a large RA of a conventional single barrier-based magnetic tunnel junction MRAM, the multiple barrier layer-based magnetic tunnel junction provided in the present application, while ensuring a high TMR, increases the tunnel polarization current transmission rate, reduces the RA, thus reducing component power consumption, and, at the same time, increases the reliability of a spin transfer torque flip process. The multiple barrier layer-based magnetic tunnel junction provided in the present invention is provided with the characteristics of low power consumption and low write error rate.
