Logic device, method, magnetic memory and computer equipment

Abstract

According to a logic device, a method, a magnetic memory and a computer equipment provided by the invention, the ferromagnet with vertical magnetic anisotropy is introduced, and compared with a ferromagnet with in-plane magnetic anisotropy, the ferromagnet with vertical magnetic anisotropy is higher in thermal stability, so that the reduction of the device is facilitated, and the density of the device is increased; meanwhile, the whole ferromagnetic body is in contact with the magnetoelectric material, and therefore it can be guaranteed that the whole ferromagnetic moment is turned over consistently, logic errors are reduced, and turning delay is reduced; furthermore, the device provided by the invention is simpler in structure, the reading unit of the device is only composed of a ferromagnetic material with perpendicular magnetic anisotropy, and a high spin-orbit coupling material is not needed, so that the density of the device is increased, the process difficulty is reduced, and the manufacturing cost of the device is saved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a logic device, method, magnetic memory and computer equipment. Background technique [0002] As the size of transistors has approached the physical limit, the high power consumption and low reliability caused by the quantum tunneling effect are limiting the further shrinkage of devices, and Moore's Law, which was effective in the past, is gradually not applicable to the development of the semiconductor industry today. In this context, spintronic devices, which use the intrinsic spin of electrons instead of charges as information carriers, are expected to replace traditional CMOS devices and continue Moore's Law. For spintronic devices, the manipulation of the magnetization direction and the detection of the magnetization state are the key to realize the logic operation. Contents of the invention [0003] An object of the present invention is to provide a logic device f...
