Latest Patents

One of Hayakawa's latest patents is a magnetic memory device and method of operating the same. This device features a loop-type magnetic track with a first part and a second part arranged in a counterclockwise direction. It includes a first conductive line on the top surface of the first part and a second conductive line on the bottom surface of the second part. The magnetic track is composed of a lower magnetic layer, a spacer layer, and an upper magnetic layer that are sequentially stacked. Each conductive line is made of heavy metal and is designed to generate spin-orbit torque caused by the current flowing through it. This spin-orbit torque enables the movement of magnetic domains in the magnetic track in either a clockwise or counterclockwise direction.

Another notable patent is for vertical variable resistance memory devices and methods of operation in the same. This device consists of gate electrodes and a pillar structure. The gate electrodes are spaced apart on a substrate in a vertical direction, which is substantially perpendicular to the upper surface of the substrate. The pillar structure extends vertically through the gate electrodes and includes a vertical gate electrode, a variable resistance pattern on the sidewall of the vertical gate electrode, and a channel on the outer sidewall of the variable resistance pattern. The channel and the vertical gate electrode are in contact with each other, enhancing the device's performance.
